Question

Formula for velocity (V) of sound waves is, where A - amplitude, T- time period, λ- wavelength and f- frequency

λ*A

λ*T

λ/A

λ*f​

Answer 1

Answer:

d option is correct which is lambda times frequency

Answer 2

Answer:

answer is

λ*f

Explanation:

Velocity is defined as

V = Distance/Time

Now , Distances of Sounds wave = λ

and time = 1/frequency

= 1/f

So

V= λ.f
