A wave traveling through water has a speed of 5 m/s. If the wavelength is 2 m, what is its frequency?

10 Hz

0.4 Hz

7 Hz

2.5 Hz

What is the relationship between frequency and wavelength (if wave speed remains constant)?

When frequency increases, wavelength increases

When frequency decreases, wavelength decreases

When frequency increases, wavelength decreases

Choose the wave behavior shown.

reflection

refraction

diffraction

constructive interference

destructive interference

A disturbance that travels through a medium as a longitudinal wave

sound

wavelength

pitch

frequency

When the sound source moves, the frequency changes
ex. police car siren sounding lower pitch after the car passes

pitch

frequency

Doppler Effect

The sound would be higher.

The sound would be lower.

The sound would be softer.

The sound would be louder.

After the train passed, the pitch of the train whistle became lower. This change in sound would be represented by what change in the diagram above?

The distance represented by C would increase.

The distance represented by C would decrease.

The distance represented by D would increase.

The distance represented by D would decrease.
