Light Waves Review

Front

What is light?

Back

Light is a form of energy that travels in waves and can be seen by the human eye.

Front

What happens when light is absorbed by a material?

Back

When light is absorbed, its energy is taken in by the material, which can cause changes in the material's properties.

Front

What is refraction of light?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is the relationship between light and color?

Back

Color is determined by the wavelength of light that is reflected off an object; different wavelengths correspond to different colors.

Front

What is the effect of sunlight on car paint over time?

Back

Sunlight can cause car paint to change color due to the absorption of light energy, which can degrade the paint.

Front

What does it mean if a material reflects light?

Back

If a material reflects light, it means that the light bounces off the surface without being absorbed.

Front

What is the significance of energy absorption in biological materials like DNA?

Back

Energy from light can damage DNA, leading to mutations and potentially increasing the risk of skin cancer.

Front

What is the difference between absorption and reflection of light?

Back

Absorption occurs when light energy is taken in by a material, while reflection occurs when light bounces off a surface.

Front

How does light energy affect skin cancer rates?

Back

Higher exposure to UV light can increase the risk of skin cancer, but other factors like skin type and protective measures also play a role.

Front

What is a false statement about light energy?

Back

Energy from light causes the same change in all types of materials (this is false; different materials react differently to light energy).
