The way a rock reflects light is called the luster of the rock. Hence option B is the correct answer.
What is Reflection?When light rays bounce off one surface, transition from one transparent medium to the next, or proceed through a media whose structure is constantly shifting, they change direction.
According to the law of reflection, the angle of the reflected ray when reflecting from a level surface is the same as the angle of the ray. (By practice, all angles in wave propagation are expressed with regards to the normal to the surface, or to the line that is perpendicular to it.
The light beam and the surface normally establish a plane in which the reflected beam is always located. The pictures created by straight and curved mirrors can be understood using the

If you have two waves, one with a frequency of 4.4 x 1010 Hz and one with a frequency of 3.6 x 1014 Hz, which has the highest energy? Justify your answer
with evidence from the lesson and/or mathematically.
Answer: frequency of 3.6 x 10^14 Hz
Explanation:
If someone have two waves, one with a frequency of 4.4 x 1010 Hz and one with a frequency of 3.6 x 1014 Hz, the one with higher frequency ( 3.6 × 10^14) will have the higher energy.
From electromagnetic spectrum,
E = hf
Where
E = energy
F = frequency
h = Planck constant
The one with higher frequency will have the higher energy since energy is directly proportional to the frequency.
The one with higher frequency ( 3.6 × 10^14) will have the highest energy.
What is the frequency?Frequency is the number of oscillations per second in the sinusoidal wave.
If someone have two waves, one with a frequency of 4.4 x 10¹⁰ Hz and one with a frequency of 3.6 x 10¹⁴ Hz.
From electromagnetic spectrum, energy associated with the frequency is
E = hf
Where, E = energy, f = frequency and h = Planck constant
The Planck's constant is the constant value. The energy is directly proportional to the frequency.
Thus, The one with higher frequency will have the higher energy since energy is directly proportional to the frequency.

Explanation:
There is a large box and a small box on a table. The same force is applied to both boxes. The large box moves two feet and the small box moves one foot. Which movement shows the most work done? The movement of the large box shows more work because the box moved a longer distance. The work done is equal because the same force was applied to both boxes. The movement of the small box shows more work because the box moved a shorter distance. The work done was equal because both boxes moved in the same direction as the force.
Answer:
The movement of the large box shows more work because the box moved a longer distance.
