The wavelength of sound at a frequency of 1,000 Hz is approximately
A)2 ft.
B)1 ft.
C)10 ft.
D)0 ft.
E)5 ft.

Question

Quizplus · Accepted Answer

The wavelength of sound at a frequency of 1,000 Hz can be calculated using the formula wavelength = speed of sound / frequency. The speed of sound in air at room temperature is approximately 1,125 feet per second. Therefore, the wavelength of sound at a frequency of 1,000 Hz is approximately 1.125 feet or 13.5 inches, which is closest to choice B of 1 ft.
