Question

A baby cries with a frequency 712 Hz, if the
speed of sound in air is 356 ms- the wave
length of sund is
1) 0.005m 2) 0.05m 3) 0.5m 4) 5m​

Answer 1

Answer:

2) 0.05m

Explanation:

Hope it helps you...

Answer 2

Answer:

3) 0.5m

Explanation:

We know that speed of sound is equal to the product of the frequency and the wavelength

Let the wavelength be x

356 = 712x

x = 0.5m

So option 3 is correct.
