Interference of waves
- It occurs when two waves merge.
- The result can be a much larger wave, a smaller wave or no wave at all.
- The amplitude of the resulting pulses is the sum of the individual amplitudes of the initial pulses.
- If the resulting pulse has zero amplitude, then the Pulses are said to have undergone complete destructive interference.
- When the amplitude of the resulting pulse is bigger than that of the individual pulses, they are said to have undergone constructive interference.
- Alternate dark and bright radial lines are seen on the paper.
