Question

a bat can hear sound at frequency upto 120kHz. what will be th wavelength of sound in air at this frequency?? (take ,speed of sound = 344m/s)

Answer 1

Velocity= wave length * frequency
            = wave length * 120 * 10^3
344/120000 = wave length
Therefore, answer would be 0.00286
So rounded off to 0.0029 OR 0.003
