Question

When the listener moves towards stationary source with velocity ' V ₁ ', the apparent frequency of emitted note is ' F₁ '. When observer moves away from the source with velocity ' V ₁ ', apparent frequency is ' F ₂ '. If' V is the velocity of sound in air and F₁ F₂ =2 then V V₁ is

Quantrex Academy · Accepted Answer

Correct answer: B. 3

aligned & F₁=F ( V+V₁ V ) F₂ & =F ( V-V₁ V ) & F₁ F₂ = ( V+V₁ V-V₁ )=2 & V V₁ =3 aligned ...(given)
