PhysicsEasysingle choice

An observer moves towards a stationary source of sound, with a velocity one-fifth of the velocity of sound. What is the percentage increase in the apparent frequency?

Options:

Answer:

Solution:

$f_{app} = f_{0} (\frac{v + v_{0}}{v})$

$\frac{f_{app} - f_{0}}{f_{0}} = \frac{v_{0}}{v} = \frac{\frac{v}{5}}{v} = \frac{1}{5} = 20 %$
