Question

The velocity of sound wave in a given medium is V when its frequency is v. The velocity, when frequency changes to 5v is

Answer 1

The velocity = 5V1 when frequency changes to 5v.

Explanation:

Given data:

Velocity = V

Frequency = v

To find velocity "V2" = ? when frequency changes to 5v.

Solution:

Speed = Frequency x wavelength

Now if the wavelength λ is held constant by artificially manipulating V and v, then,

λ =V1 / v1= V2 / v2

Therefore

Speed = Frequency x wavelength

V2 = v2 / v1 x V1

V2 = 5v1 / v1 x V1

V2 = 5V1

Answer 2

Answer:

V=V when f =v

V"=? when f=5v

V"=5V

Explanation:

Because

Velocity=frequency×wavelength

So....5f×wavelength=5V
