Two cars A and B approach a stationary observer from opposite side as shown in fig.Observer hears no bears. If the frequency of the horn of the car B is 504 Hz, the frequency of horn of car A will be:
Options
A.529.2Hz
B.295.2Hz
C.440.5Hz
D.non of these
Solution
Since the person hears no beats therefore their apparent are the same.
So, n ×
= 504 × 
n =
= 529.2Hz
So, n ×
= 504 × n =
= 529.2HzCreate a free account to view solution
