A source of sound of single frequency v₀ flies along a straight line which is at a finite distance from the observer. Then the observer hears

Options

  1. Aa frequency v₀ at the instant when the source is nearest to him
  2. Ba frequency greater than v₀ the instant when the source is nearest to him
  3. Ca frequency v₀ at an instant later than the instant of nearest position of the source
  4. Dthe variation of frequency with time is linear.

Correct answer

C. a frequency v₀ at an instant later than the instant of nearest position of the source

Step-by-step solution

When source is nearest than frequency heard. f^ = f C C-V_s after crossing this point frequency obtained corresponding to wave emitted from this point is f ^ = f ₀
