Question

a bat can hear sound of frequency upto 120khz Determine the minimum wavelength of same in air to be 344m/s​

Answer 1

Answer:

2.87x10^-3 m

Explanation:

Given that,

Frequency,f = 120 kHz

= 120x1000 Hz

= 120000 Hz

Velocity,v = 344 m/s

We know,

v= f x lamda

lamda = v/f

= 344/120000

= 2.87 x 10^-3 m
