Answer:spectrum

Explanation:

Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.

So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.

But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.

So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?

The electromagnetic waves are:

Radio
Micro
Infrared
Visible light
Ultra violet
X-ray
Gamma

(I remember them using the mnemonic “Read My Instructions Visible Under X-ray Glasses” (first letter of each word represents an EM wave))

Only Visible light waves are visible to the human eye

Explain your answer using evidence from the Sim.

Answers

Based on evidence from Sim, when two substances were combined they did not change into different substances.

Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.

They just combine together and form a new substance.

Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.

The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.

Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.
