AP Unit 10 Waves Review - JCS

The very top point of a wave is called a..

• Trough

• amplitude

• Medium

• Crest

The speed of a wave is equal to:

• the amplitude divided by the frequency.

• the wavelength multiplied by the frequency

• the amplitude multiplied by the frequency.

• the wavelength divided by the frequency.

The string on a guitar is observed to vibrate at frequencies of 320 hertz,380 hertz and 440 hertz. The string's fundamental frequency is.

• 60 hertz

• 160 hertz

• 320 hertz

• 440 hertz

A wave is:

• an oscillation that travels from one place to another.

• a frequency that is resonant with a periodic force.

• a system in steady harmonic motion.

• an unstable oscillation that rapidly decays to zero amplitude.

Due to the Doppler effect, it a sound (like a train ) is moving toward you, how will the sound change as it approaches?

• Pitch sounds lower

• amplitude sounds lower

• amplitude sounds higher.

• Pitch sounds higher

Wave that do not require a medium are called...

• Electromagnetic wave

• Transverse wave

• sound wave

• Compression wave

When two or more waves combine to form a single wave, it is called.....

• wavelength

• Interference

• standing wave

• frequency

which of the following is sound unable to travel through?

• Air

• Water

• Gas

• Vacuum / Space

Resonance is standing waves is caused by:

• interference with reflections from boundaries.

• loss of energy due to absorption.

• the product of frequency multiplied by wavelength,

• the wavelength being smaller than the smallest distance between the boundaries.

which of the following increases as the frequency of the sound increases?

• amplitude

• intensity

• loudness

• pitch
