Sound can travel through a vacuum.

Intense sounds are usually perceived as loud sounds.

The speed of a sound wave depends upon its frequency and its wavelength.

Sound waves travel fastest in solids (compared to liquids and gases) because solids are more dense.

The speed of a wave within a guitar string varies inversely with the tension in the string.

A high pitched sound has a low wavelength.

A low-pitched sound is a sound whose pressure fluctuations occur with a low period.

Both low- and high-pitched sounds will travel through air at the same speed.

What type of wave is produced when the particles of the medium are vibrating to and from in the same direction of wave propagation?

The main factor which effects the speed of a sound wave is

As a wave travels into a medium in which its speed increases, its wavelength

Doubling the frequency of a sound source doubles the speed of the sound waves which it produces.

A sound wave has a wavelength of 3.0 m. The distance between the center of a compression and the center of the next adjacent rarefaction is

Which one of the following factors determines the pitch of a sound?

Consider the diagram below of several circular waves created at various times and locations. The diagram illustrates

In the diagram above, a person positioned at point A would perceive __________ frequency as the person positioned at point B.

A girl moves away from a source of sound at a constant speed. Compared to the frequency of the sound wave produced by the source, the frequency of the sound wave heard by the girl is ____

The average wavelength in a series of ocean waves is 15.0 m. A wave crest arrives at the shore on average every 10.0 s, so the frequency is 0.100 Hz. What is the average speed of the waves?

 $v=f\times\lambda$  

The speed of sound in air is about 340 m/s. What is the wavelength of a sound wave with a frequency of 220 Hz 

 $v=f\times\lambda$  

Half the vertical distance between the crest and trough of a wave is called the

The number of waves passing a given point per unit of time is called the

The Doppler effect of a passing siren results from an apparent change in

The combining of waves as they meet is known as

Identify each of the following as a distance measurement

Identify each of the following as a time measurement

 $v\ =f\times\lambda$  

Ocean waves are hitting a beach at a rate of 2.0 Hz. The distance between wave crests is 1.5 m. Calculate the speed of the waves.

 $v=f\times\lambda$   

The note A above middle C on a piano emits a sound wave with wavelength 0.77 m. What is the frequency of the wave? Use 340 m/s as the speed of sound in air.

All the waves shown have the same speed in the same medium. Rank these waves from most to least for wavelength.
