A Back and forth motion that repeats itself is a

The number of vibrations that occur in one s is called

Frequency is measured in units of

The maximum displacement from rest to the crest or from rest to the trough of a wave is called

A wave with motion perpendicular to the direction that the wave is moving is classified as a

Your brain interprets a frequency as a sound with a certain

Sound waves with frequencies greater than 20000 hz are

Generally sound travels faster in

Sound travels faster in

The bending of a wave front between boundaries is

A reflected sound that reaches the ear within .1 s after the original sound results in

The wave front of a refracted sound bends toward

Two in-phase sound waves with the same amplitude and frequency arrive at the same place at the same time resulting in

Two out of phase sound waves with the same amplitude and frequency arrive at the same place at the same time resulting in

Two sound waves of equal amplitude with slightly different frequencies will result in

Two sound waves of unequal amplitudes with different frequencies will result in

The energy of a sound wave is proportional to the weight of energy transferred to an area perpendicular to the waves which is called the sound

A decibel noise level of 40 would be most likely found

A resonant condition occurs when

The fundamental frequency of a string is the

The fundamental frequency on a vibrating string is what part of a wavelength

Higher resonant frequencies that occur at the same time as the fundamental frequency are called

A moving source of sound or a moving observer experiences the apparent shift in frequency called

Does the Doppler effect occur when the observer is moving and the source of sound is stationary
