Doppler Effect in Moving Medium

Doppler Effect in Moving Medium

### Formula

$$f'=f\frac{v+v_o}{v-v_s}$$

### Terminologies

- f' → Observed frequency.

- f → Actual frequency.

- v → Velocity of sound relative to medium.

- vo → Observer velocity.

- vs → Source velocity.

### Conditions / Special Cases

- Velocities are measured with respect to medium.

### Usage

- Used in advanced Doppler effect problems.
