Refraction, Reflection and Absorption (ALL)

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is absorption in terms of light?

Back

Absorption is when light is taken in by a material and not reflected or transmitted.

Front

What happens when light hits a mirror?

Back

It bounces off the mirror.

Front

When light waves bounce off a surface we call this:

Back

Reflection.

Front

A longitudinal wave's oscillations move ___________________________ to its energy transfer.

Back

Parallel.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow light to pass through clearly, translucent materials allow some light to pass but scatter it, and opaque materials do not allow light to pass through.
