Difference between spherical wavefront and plane wavefront
Answers
Diferentiate between plane wavefront and spherical wavefront.
1. What is wavefront and wavelet?
Ans: The locus of vibrating particles in medium travelling in some phase at that instant is called wavefront. The new spherical wave originating from wavefront of the wave which travels with the speed of wave at that medium is called wavelet.
2. Diferentiate between plane wavefront and spherical wavefront.
Ans: If the source of light is point source, then the locus formed at any instant is called the spherical wave front. If the source of light is in infinite distance, then the wavefront formed is called plane wavefront.
3. How can we change spherical wavefront to plane wavefront and vice versa?
Ans: We can interchange from one form to another form by using convex lens. When a spherical wavefront is kept at the focus of the lens, it changes into plane wavefront. Likewise if convex lens is kept in the path of plane wavefront, spherical wavefront is formed.
