A stationary source sends forth monochromatic sound. A wall approaches it with velocity 33 cm/s. The propagation velocity of sound in the medium is `c=330(m)/(s)`. How much, in per cent , does the wavelength of sound change on reflection from the wall?

if the velocity of sound in helium at room temperature is 330 m/s, then the velocity of sound in hydrogen is

if the velocity of sound in helium at room temperature is 330 m/s, then the velocity of sound in hydrogen is

A driver in a stationary car horns which produces monochromatic sound waves of frequency n=1000Hz , normally towards a reflecting wall. If the wall approaches the car will a velocity u=3.3(m)/(s) , calculate the frequency of sound reflected from wall and heard by the driver. What is the percentage change of sound frequency of reflection from the wall?
