Unit 2 Test Review: Waves

Front

What is reflection in the context of waves?

Back

Reflection is the bouncing back of a wave when it hits a surface that does not absorb the wave's energy.

Front

What happens to light when it is reflected?

Back

When light is reflected, it changes direction but remains in the same medium.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the matter moves in the same direction as the wave travels.

Front

What is the primary function of a wave?

Back

A wave is a disturbance that transfers energy from one place to another.

Front

How does amplitude relate to wave energy?

Back

The larger the amplitude of a wave, the more energy it carries.

Front

What is refraction?

Back

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

Front

What is absorption in wave behavior?

Back

Absorption is when a wave's energy is taken in by the material it encounters, rather than being reflected or transmitted.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of waves, while refraction is the bending of waves as they enter a different medium.

Front

What is a wave?

Back

A wave is a disturbance that travels through space and matter, transferring energy.

Front

What is the relationship between wavelength and energy?

Back

Generally, shorter wavelengths carry more energy than longer wavelengths.
