when light strikes a window pane some rays will be reflected back and forth in between the two glass surfaces. why do these reflected rays not produce visible colored interference fringes?

Answers

Answer 1

Yes, and the colors you see will now be the colors your eye perceives when you see the wavelengths producing the interference patterns.

In physics, the wavelengths is the length over which a periodic wave repeats or its spatial period. It is the separation between neighboring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both traveling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.

Wavelength is inversely related to frequency for a sinusoidal wave flowing at a constant speed.

Answer 2

The reflected rays of light do not produce visible colored interference fringes in a window because the glass structure of a window pane prevent.

In the case of the window pane, it is true that the light is still reflected on the front and rear surface of the glass. the reflecting medium need to have a thickness that the that is comparable to the wavelength of light. windows are simply too thick. Due to the structure of glass, No Interference. In the case of thin film both reflected rays belong to the same waveform. light striking a film is partially reflected and partially refracted at the top surface. the refracted ray is partially reflected at the bottom.

❧ What is the dispersion of White Light?

Answers

When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.

What causes the dispersion of white light?Cause of Dispersion: When white light passes through a glass prism, its constituent colours (red, orange, yellow, green, blue, indigo, violet) travel with different speeds in the prism because refractive index is color dependent. This causes the dispersion of light.The bending of the colors when they pass through the prism depends on its wavelength. So violet color has a shortest wavelength as a result it bends the most and followed by indigo, blue, green, yellow, orange and red respectively.The splitting of light into its component colors is called dispersion of light. Dispersion of white light can be done by a glass prism. The inclined refracting surface of a glass prism shows this phenomena.When a prism is placed in a room and a beam of white light is allowed to fall on one of its refracting faces. It is found that light coming out from the other face of the prism is split into seven colors (violet, indigo, blue, green, yellow, orange, red).

The three ways to acceleration a moving vehicle are to depress the accelerator pedal, depress the brake, push the vehicle, or exert external force.

The rate at which the velocity of an object varies in relation to time is known as acceleration. Accelerations exist in vector quantities (in that they have magnitude and direction). The object's acceleration is determined by the direction of the net force acting on it. The size of the net balance of all external forces acting on the item is, in accordance with the materials used to create it, inversely proportional to its mass, but the magnitude of the net resultant force is directly proportional to the net force.

A moving object's rate of change in direction and speed over time is called acceleration. It is said to be accelerating when anything goes faster or slower. Due to the frequent change in direction, motion on a circle accelerates even while the speed is constant.

The total internal reflection can occur when light is traveling from glass to its interface with air.

Total internal reflection occurs when light moves from denser to rarer and the angle of incidence is greater than the critical angle.

Total Internal Reflection occurs when light travels from water to air, but it does not occur when light travels from air to water. Total Internal Reflection would occur for light travelling from water to air, but not for light travelling from water (n=1.333) to crown glass (n=1.52). TIR occurs when the angle of refraction approaches 90 degrees before the angle of incidence approaches 90 degrees. Light can only bend away from the normal if the angle of refraction is greater than the angle of incidence. Because light only bends away from the normal when passing from a denser medium to a denser medium, this would be a necessary condition for total internal reflection.

The complete question is as follows:

you now take three pieces of string from the previous problem and tie two of them together to make a string of double the mass density. you tie the single string and double string together and to two lamp posts that are 40 m apart as seen below. the interface is centered between the posts and the tension is 1.2 n. you briefly shake the string interface at 5 hz. By how many seconds does it win the race?

Answers

Taking three pieces of string from the previous problem and tie two of them together to make a string of double the mass density, V₁ = [tex]\sqrt{2}[/tex]V₂ it wins the race.

What is the mass density?

An object's mass per unit volume is referred to as its mass density. The units that can be used to describe this characteristic are pounds per square foot (lb/ft²) and kilograms per square meter (kg/m³).

Given that,

tension = 1.2 N

Frequency = 5 Hz.

Length = 40 m

Let, mass density of thin string = m

mass density of thick string = 2m

As we know,

V₁ = [tex]\sqrt{F/m}[/tex]

V₂ = [tex]\sqrt{F/2m}[/tex]

Now,

V₁/V₂ = [tex]\sqrt{F/m} / \sqrt{F/2m}[/tex]

or, V₁/V₂ =  [tex]\sqrt{2} /1[/tex]

or, V₁ = [tex]\sqrt{2}[/tex]V₂

Thus, speed of the thin string is [tex]\sqrt{2}[/tex] times greater than the speed of the thick string. So, it will comes first.

This one is a challenge
A motorcycle traveled north along a straight path for 2.22 hours with an average velocity of 67.8 km/h, stopped for 20.0 min, then traveled north for 3.33 hours with an average velocity of 77.7 km/h.
What is the average velocity for the trip?
What is the displacement for the entire trip?

Answers

Vavg=dx/dt
Where
Vavg - average velocity
dx - total displacement
dt - total change in time (in fact the amount of time spent from the beginning of the motion)

dx = 2.22*67.8 + 3.33*77.7 = 409.3 km
(Since motorcycle traveled in the same direction - North)
dt = 2.22 + 3.33 + 0.33 = 5.9

Vavg = 409.3 / 5.9 = 69.4 km/h

Answer:

Explanation:

1 track section:

V₁ = 67.8 km/h

t₁ = 2.22 h

2nd track section:

V₂ = 0 km/h

t₂ = 20.0 min = (1/3) h ≈ 0.33 h

3 track section:

V₃ = 77.7 km/h

t₃ = 3.33 h

___________

V - ?

D - ?

Length of 1 track section:

D₁ = V₁·t₁ = 67.8·2.22 ≈ 150.5 km

Length 2 sections of track:

D₂ = V₂·t₂ = 0·0.33 = 0 km

Length 3 sections of track:

D₃ = V₃·t₃ = 77.7·3.33 ≈ 258.7 km

Summary path:

D = D₁ + D₂ + D₃ = 150.5 + 0 + 258.7 =  409.2 km

Total time:

t = t₁ + t₂ + t₃ = 2.22 + 0.33 + 3.33 = 5.88 h

Average speed:

V = D / t = 409.2 / 5.88 ≈  69.6 km/h

A 20.0cm massless spring with spring constant 340N/m is suspended from the ceiling. A student carefully hangs a 450g mass from the free end. How long is the spring now?

Answers

After hanging the mass, the length of the spring is 21.3 cm using Hooke's law.

What is Hooke's law?

According to the physics principle known as Hooke's Law, the force required to expand or compress a spring by a given distance is inversely proportional to that distance.

The first traditional example of an explanation of elasticity is Hooke's law. Elasticity is the quality of a substance or item that allows it to return to its original shape after distortion. A restoration force is a capacity to restore the original shape after experiencing distortion.

Given,

Equilibrium length of the massless spring = 20 cm

Spring constant k = 340 N/m

The spring is suspended from the ceiling.

Mass at the free end = 450 g

= 0.45 kg

A force is applied vertically downward on the spring due to the suspended mass which is equivalent to the weight of the mass i.e.

F = mg             ... (1)

This force is balanced by the spring. If the spring is extended by a length of  due to the suspension of the mass then by Hooke's law,

F = kx              ... (2)

From equation (1) and (2)

mg = kx

x = mg/k

Put all the values

x = (0.45)(9.8)/(340)

= 0.013 m

= 1.3 cm

So, the length of the spring is

l = 20 + 1.3

= 21.3 cm
