Question

10. Give the examples of the experiments based on division of wave front
​

Answer 1

Answer:

The instruments used to obtain interference by division of wavefront are the Fresnel biprism, Fresnel mirrors, Lloyd's mirror, lasers, etc. Division of Amplitude: In this method, the amplitude of the incident beam is divided into two or more parts either by partial reflection or refraction.

Answer 2
