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
