A tuning fork has a frequency of 300 Hz and produces a sound wave with a wavelength of 4 feet. What is the velocity of sound in air?

Answer: 1200 ft/sec
Explanation

The velocity of sound is calculated using the formula:

Velocity=Frequency×Wavelength

Given:

Frequency = 300 Hz

Wavelength = 4 ft

Velocity=300×4=1200 ft/sec
