What is meant by coherent sources of light?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Coherent Sources**: Coherent sources of light are defined as two light sources that emit waves with specific characteristics. 2. **Same Frequency**: The first characteristic of coherent sources is that they produce waves with the same frequency. This means that the number of wave cycles produced per unit time is identical for both sources. 3. **Same Waveform**: The second characteristic is that the waves produced by these sources have the same waveform. This indicates that the shape of the wave (such as sine wave, square wave, etc.) is identical for both sources. ...
