a) Suppose the velocity of a wave in string depends on the tension in the string, mass of the
string and the length. Show that V = (b) briefly explain the concept of Doppler Effect. (11) A
νμ
car approaches a large stationary reflector R with a velocity of 20m/s when sounding a note of
1000Hz from its homs. Another car B behind A is also traveling towards A with a velocity of
30m/s. Estimate the apparent frequencies noticed by driver of car B.
