Waves

Front

What must light be in order for the material to be affected by it?

Back

Absorbed.

Front

What is the highest point on a transverse wave called?

Back

Crest.

Front

What is the lowest point on a transverse wave called?

Back

Trough.

Front

What type of waves include sound waves and earthquake P-waves?

Back

Longitudinal waves.

Front

What is a vacuum?

Back

A space with NO matter at all present.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel.

Front

What happens to light when it is absorbed by a material?

Back

The energy from the light is transferred to the material, potentially causing changes.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second.

Front

What is refraction?

Back

The bending of light as it passes from one medium to another.

Front

What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resulting wave is the sum of the individual waves.
