Reflection, Refraction, Absorption

Front

What is Refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, such as from air to water.

What is Reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface, such as a mirror.

What is Absorption?

Back

Absorption is the process by which light waves are taken in by a material, converting the light energy into other forms of energy.

How does light behave when it travels from air to water?

Back

When light travels from air to water, its speed decreases and it bends towards the normal line.

What is the normal line in optics?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence where light strikes.

What is the difference between reflection and refraction?

Back

Reflection involves bouncing off a surface, while refraction involves bending as light passes through different media.

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to reflect entirely back into the medium.
