Question

Coherent sources can be created by the division of

Answer 1

Coherence:

1. The coherent source emits the light waves with the same frequency, wavelength, and the phase difference between the waves remains constant such that it cause stationary interference.
2. These phenomena don't usually occur in reality but allow a brief understanding of waves.
3. It has become an important concept in quantum physics.

The coherent source can be produced by the following methods:

By dividing the wavefront:

1. A wavefront can be broken into sections.
2. It can be utilized with various lenses, mirrors, and prisms.
3. Some of the methods include Young's double-slit experiment, Lloyd's mirror arrangement, and Fresnel's biprism method.

By dividing the Amplitude:

1. A coherent source can be formed by dividing the amplitude of an incoming light beam.
2. This can be accomplished by the partial reflection or refraction process.
3. These split components then collide with one another, causing interference.

Therefore, coherent sources can be created by the division of wavefront and also by the division of amplitude of the wave.
