What is infrared light?

Back

Infrared light is a type of electromagnetic radiation that has a longer wavelength than visible light and is not visible to the human eye. It can carry energy and heat.

Front

How does light affect the color of objects?

Back

Light can affect the color of objects by providing energy that can be absorbed by pigments in the material, causing a change in color.

Front

What is the role of energy in color change?

Back

Energy from light can be absorbed by materials, leading to a change in their physical properties, such as color.

Front

What happens when light hits a mirror?

Back

When light hits a mirror, it reflects off the surface. Mirrors do not absorb light energy, which is why they do not change temperature significantly.

Front

What is the difference between visible light and infrared light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye, while infrared light has longer wavelengths and is not visible.

Front

Can light cause materials to heat up?

Back

Yes, certain types of light, especially infrared light, can cause materials to heat up by transferring energy to them.

Front

What is energy absorption in materials?

Back

Energy absorption in materials occurs when light energy is taken in by the material, which can lead to changes in temperature or color.

Front

Why does infrared light warm objects?

Back

Infrared light warms objects because it carries energy that can be absorbed by the material, increasing its temperature.

Front

What is the effect of sunlight on special color-changing paper?

Back

Sunlight can cause special color-changing paper to change color by providing energy that the paper absorbs.

Front

How does energy transfer occur with light?

Back

Energy transfer with light occurs when light waves interact with materials, leading to absorption, reflection, or transmission of energy.
