A source and listener are both moving towards each other with speed V 10 . (where V is speed of sound) If the frequency of sound note emitted by the source is ' n ', then the frequency heard by the listener would be nearly

Options

  1. A1.1 n
  2. B1.22 n
  3. Cn
  4. D1.27 n

Correct answer

B. 1.22 n

Step-by-step solution

aligned n ^ & = ( V + V _ L V - V _ S ) n & = ( V + V 10 ~V - V 10 ) n & = 11 9 n & =1.22 n aligned
