S8P4 - Waves Review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What do waves carry or transmit?

Back

Waves carry or transmit energy.

Front

What is the difference between a convex lens and a concave lens?

Back

A convex lens converges light rays, while a concave lens diverges light rays.

Front

What happens to light when it passes through a convex lens?

Back

Light rays converge to a focal point after passing through a convex lens.

Front

What happens to light when it passes through a concave lens?

Back

Light rays diverge after passing through a concave lens.

Front

What is reflection?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

What is refraction?

Back

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

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What is the focal point of a lens?

Back

The focal point is the point where light rays converge or appear to diverge after passing through a lens.

Front

What is the difference between energy and matter in the context of waves?

Back

Energy is transmitted by waves, while matter is not carried along with the wave.
