Behaviors of Waves Review

Front

What happens to the pitch of a sound when the source moves toward you?

Back

The pitch of the sound becomes higher.

Front

What happens to the pitch of a sound when the source moves away from you?

Back

The pitch of the sound becomes lower.

Front

What is the formula for Snell's Law?

Back

n₁sin(Θ₁) = n₂sin(Θ₂)

Front

What is the index of refraction of a material if light travels from air (n=1.00) into it at an angle of 43° and refracts at an angle of 27°?

Back

1.5

Front

What do we hear when a sound wave reflects off a surface?

Back

An echo.

Front

What happens to light when it travels from water to air?

Back

It speeds up.

Front

Define 'refraction' in the context of waves.

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is the relationship between frequency and pitch in sound waves?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the effect of a medium on the speed of sound?

Back

Sound travels at different speeds in different media; it travels fastest in solids, slower in liquids, and slowest in gases.

Front

What is an example of a wave experiencing reflection?

Back

Sound waves bouncing off a wall and returning to the listener.
