Question

A sound of wavelength 68cm travels 850m in 2.5s calculate the velocity of sound and frequency of sound

Answer 1

Answer:

speed = 340 $ms^{-1}$

frequency = 5hz

Explanation:

speed = distance / time = 850/2.5

speed = 340 $ms^{-1}$

wavelength * frequency = speed

frequency = speed / wavelength = 340/68

frequency = 5hz

Answer 2

Answer:

velocity of sound is 340m/s

the frequency of sound is 5 hz
