A sound wave of frequency f travels horizontally to the
right. It is reflected from a large vertical plane surface moving
to left with a speed v. The speed of sound in medium is c.
Then
(a) the number of wave striking the surface per second is
f (c + v)/c
(b) the wavelength of reflected wave is c(c + v)/f (c + v)
(c) the frequency of the reflected wave is f (c - v)/(c - v)
(d) the number of beats heard by a stationary listener to
the left of the reflecting surface is vf/c - v
