A stationary observer receives sonic oscillations from two tuning forks, one of which approaches and the other recedes with same speed. As this takes place the observer hears the beat frequency of 2 Hz. Find the speed of each tuning fork,(assuming it is very small when compared to sound) if their oscillation frequency is 680 Hz and the velocity of sound in air is 340 m/s.  
  • a)
    1 m/s  
  • b)
    2 m/s  
  • c)
    0.5 m/s  
  • d)
    1.5 m/s 
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A stationary observer receives sonic oscillations from two tuning fork...
Let the frequencies be f1 and f2
So, f1 = f (vs/vs - v) and f2 = f (vs/vs + v)
ATQ: f1 – f2 = 2 Hz
