Question

sound waves of wavelength 1 cm have a velocity of 340 m/s in air what is their frequency?​

Answer 1

Answer:

speed= wave length × frequency

so ,

f=speed /wave length

(wave length =1cm=0.01m)

f=340/0.01

f=34000anwer

Answer 2

Explanation:

velocity = wavelength × frequency

frequency =velocity /wave

so f =340 ×10^2
