Q. A source of sound moves towards a stationary listener. The apparent pitch of the sound is found to be higher than its actual value. This happens because

Waves

Solution:

Source is moving forwards the observer.
$\therefore $ wavelength of sound waves decreases frequency will get increases.
$V =\left(\frac{ V }{ V - V s }\right) Vo$
$V s =$ Velocity of source.
$V =$ Velocity of sound.
