Question

(7) A sound wave has wavelength 0.86 m and
speed 344 m/s in air. If its wavelength in a gas in
0.8 m, find the speed of sound in the gas.​

Answer 1

Answer:

frequency=400Hz

Speed=320m/s

Explanation:

wavelength of sound =0.86

speed in air=344m/s

frequency=velocity/wavelength

F=344/0.86=400Hz

speed of sound=400*0.8=320m/s

I hope this is correct and helpful for u..
