Doppler Effect for Light Waves

Doppler Effect for Light Waves

### Formula

$$\frac{\Delta\lambda}{\lambda}=\frac{v}{c}$$

### Terminologies

- Δλ → Change in wavelength.

- λ → Original wavelength.

- v → Relative velocity.

- c → Speed of light.

### Conditions / Special Cases

- Valid for low velocities:

$$v\ll c$$

### Usage

- Used in astronomy and spectral analysis.
