Question

A source producing 1500 sound in 3 seconds if the wavelength of sound is 68cm then the velocity of sound wave will be

Answer 1

a source producing 1500 sounds for 3 seconds = 1500/3= 500
500/68=125/17 is correct

Answer 2

Answer:

Wavelength= 68cm

Distance=850m

Time=2.5 sec

1) Velocity=distance/ time taken=850/2.5=340 m/s

2)Frequency=Velocity/ Wavelength= 340/.68= 500Hz
