Answer to Question #102523 in Optics for MM

Question

Discuss the dependence of image forming ability of an optical device on the phenomenon of diffraction.

Answer 1

When a ray of light is passing through the lens of the optical device, then the ray of light is getting diffract, and the the diffracted light become the new source of wave after the interference. So to avoid this diffraction, we are using a larger aperture of the the to avoid the diffraction.
