Light and Matter

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 is reflection?

Back

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

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What does transparent mean?

Back

Transparent refers to materials that allow all light to pass through, such as air, water, and clear glass.

Front

What is absorption in terms of light?

Back

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

Front

What is a one-way mirror?

Back

A one-way mirror is a reflective surface that allows light to pass through from one side while reflecting light from the other side, most effective when there is a large difference in light levels.

Front

Can light be reflected off of clear glass?

Back

Yes, light can be reflected off clear glass, which is why we can see our reflection in a window.

Front

What happens to light when it hits a smooth, shiny surface?

Back

When light hits a smooth, shiny surface, it is reflected.

Front

What is the difference between transparent and opaque materials?

Back

Transparent materials allow light to pass through, while opaque materials do not allow any light to pass through.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.
