Physics · Waves and Acoustics
If the observer and the source are moving away from each other along the line of sight with speeds 'v' and 'V' respectively, then according to the Doppler effect in sound, the relationship between the source frequency (μ0) and observed frequency (μ) is given by (where 'c' = speed of sound):

- 1μ = μ0(1 - V/c1 + V/c)
- 2μ = μ0(1 + V/c1 - V/c)
- 3μ = μ0(1 - v/c1 + V/c)✓
- 4μ = μ0(1 + v/c1 - V/c)
Correct answer
μ = μ0(1 - v/c1 + V/c)
