Phys 11 Resonance and the doppler effect

What kind of beat is studied in physics?

• Rhythmic beat

• Acoustical beat

• Electronic beat

• Bass drop beat

What results in a wave diminishing?

• Damping

• Resonance

• Beating

• The Doppler effect

The resonant frequency is also known as the

• Beat frequency

• Acoustical frequency

• Natural frequency

• Doppler frequency

True or false: Speeds of vehicles on earth can cause the Doppler effect on light

• True

• False

The the source of a wave is moving towards you, the frequency

• Increases

• Decrease

• Stays the same

Can the Doppler effect be caused if the observer is moving?

• Yes

• No

If you seen a wave with a uniform pattern, you should classify it as

• Noise

• Music

• Depends on if you like it or not

What characteristic of sound depends on the amplitude?

• Beat

• Loudness

• Pitch

• Quality

What characteristic of sound depends on the harmonics?

• Beat

• Loudness

• Pitch

• Quality

A string instrument would be very quiet without having a
