Light Waves Review

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

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

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

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

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

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

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

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

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.

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