Interference in Waves

Interference is the phenomenon of two waves overlapping with each other and producing a resultant wave. The interference can occur in different types of waves, which are:

1. Transverse Waves:
In transverse waves, the particles of the medium oscillate perpendicular to the direction of wave propagation. Examples of transverse waves are water waves, electromagnetic waves, etc. Interference can occur in transverse waves when two waves meet each other, and the amplitude of the resultant wave is the sum of the amplitudes of the individual waves.

2. Longitudinal Waves:
In longitudinal waves, the particles of the medium oscillate parallel to the direction of wave propagation. Examples of longitudinal waves are sound waves, seismic waves, etc. Interference can occur in longitudinal waves when the compression and rarefaction of the waves meet each other, and the amplitude of the resultant wave is the sum of the amplitudes of the individual waves.

3. Electromagnetic Waves:
Electromagnetic waves are transverse waves that consist of oscillating electric and magnetic fields. Examples of electromagnetic waves are radio waves, microwaves, light waves, X-rays, etc. Interference can occur in electromagnetic waves when two waves meet each other, and the amplitude of the resultant wave is the sum of the amplitudes of the individual waves.

Conclusion:
Therefore, the correct answer is option 'D' - all of these, as interference can occur in transverse waves, longitudinal waves, and electromagnetic waves.
