Question

In steel sound speed of 6000 metre per second find the frequency if the wavelength is 1.5m

Answer 1

Answer:

4000 Hz

Hope it helps........

Answer 2

Answer:

f = 4000 hz

Explanation:

here V = speed of steel , f = frequency and

(λ) = wavelength

we know that , V = f (λ)

=> f = V / (λ)

=> f = 6000/1.5

=> f = 4* 10³ hz

=> f = 4000 hz (answer )
