Study Notes

Wave Interference

When waves from two coherent sources arrive in phase at the same place, they reinforce each other, resulting in constructive interference, and the amplitude of the resulting wave is greater than that of the individual waves.

Coherent Sources

Coherent sources are characterized as sources that emit waves of the same frequency and are in phase with each other.

Superposition Principle

The principle of superposition states that when two or more waves overlap in space and time, the resulting wave is the sum of the individual waves.

Anti-Phase Arrival

When waves from two coherent sources arrive in anti-phase at the same place, they cancel each other out, resulting in destructive interference, and the amplitude of the resulting wave is zero or nearly zero.
The effect of waves arriving in anti-phase from two coherent sources is destructive interference, resulting in a reduction or elimination of the wave amplitude.
