A source of sound producing wavelength \( 50 \mathrm{~cm} \) is moving away from a stationary observer with
\( \mathrm{P} \) \( \left(\frac{1}{5}\right)^{\text {th }} \) speed of sound. Then what is the wavelength

W of sound received by the observer?
(1) \( 55 \mathrm{~cm} \)
(2) \( 40 \mathrm{~cm} \)
(3) \( 60 \mathrm{~cm} \)
(4) \( 70 \mathrm{~cm} \)
