Problems A musical instrument produces a sound wave with a frequency of 1000 Hz. The sound wave has a wavelength of 0.34 m in air. Calculate the speed of the sound wave in air.

What is the period of a wave with a frequency of 1000Hz?

A submarine uses sonar to measure the depth of water underneath them. If the sound waves travel 1350m/s under water and the echo is heard 0.21 seconds after, how deep is the water under the sub?

Ocean waves with a wavelength of 120 m are coming in at a rate of 8 waves per minute. What is the speed of the waves?

Waves

Waves are a transfer of energy. They come in two common forms:

transverse and longitudinal

2

A wavelength is the distance between which two points?

The amplitude is the distance between which two points?

Red light has a wavelength of 7.00 x 107nm. If light travels at 3.00 x 108m/s, what is the frequency of the red light?

In which will sound move faster:

Water or air

Warm air or cold air

Steel or water

What is the speed of sound in air if a note with 380Hz has a wavelength of 0.87m?

How many waves are shown on the diagram to the left?
