1.	Obtain an expression for the aparent frequency of sound when the source of sound and the listener are movingaway fromeach other
Answer» Solution :For a source moving AWAY from an observer ( ASSUMED to be at REST ) apparent frequency of SOUND `f = f_(0) ((v)/( v+ v_(s)))` thereby WAVELENGTH `lambda = (v+v_(s))/( f_(0))` For an observer movingaway from the source , apparentfrequency, `f'= ( v- v_(0))/(lambda ) `i.e. `f' = f_(0)"" ((v-v_(0)))/( ( v+ v_(s)))` Note `:` For `v_(0) lt lt v, v_(S) lt lt v ` `f' = f_(0) (1- ( v_(0))/(v)) ( 1- ( v_(s))/(v))`
