Phys Science Chapter 10 Quiz

A sonic boom cannot be produced by

An aircraft flying slower than the speed of sound

The reflection of sound is

Echo

When we consider how frequently an oscillating system vibrates we're talking about

Frequency

Strings that have more mass on a musical instrument than others produce notes of

Lower frequency

When we consider the time for an oscillating system to make a vibration we're talking about

Period

Sound travel faster in

Steel

The compressions and rarefractions in a longitudinal wave travel in

The same direction

Loudness of a sound is most closely related to

amplitude

The vibrations of a transverse wave move in a direction

at right angles to the direction of wave travel

When sound waves superimpose they can interfere

constructively or destructively

Repeatedly tap the side of a drinking glass with a spoon while filling it with water and you will notice that the pitch of the sound

decreases

What moves from place to place in wave motion is

energy

A shock wave is produced when the speed of an object

exceeds the speed of sound in air

A sound wave is a

longitudinal wave

During a single period, the distance traveled by a wave is

one wavelength

To say that one wave is out of phase with another is to say that the waves are

out of step

A sound source of high frequency emits a high

pitch

Some singers are able to shatter a crystal chandelier with their voice, which illustrates

resonance

When you tune a radio to a certain station, you match the frequency of the internal electrical circuit to the frequency of that radio station, which illustrates

resonance

An acoustical engineer in designing a music hall is concerned with

reverberations
