Question

Binoculars and microscopes are frequently made

with coated optics by adding a thin layer of trans-

parent material to the lens surface as shown to

minimize reflection of incident light. One wants

(1) destructive interference between waves

1 and 2

(2) destructive interference between waves

3 and 4

(3) constructive interference between waves

1 and 3

(4) none of these​

Answer 1

Binoculars and microscopes are frequently madewith coated optics by adding a thin layer of transparent material to the lens surface as shown to

minimize reflection of incident light. One wants destructive interference between waves 3 and 4

Option 2

Explanation:

• when two or more light of the same frequency interfere with each other and result in the increase or decrease in the the amplitude of the resulting wave it is known as interference of a light.

• when we use a microscope or a telescope the outer surface is coated with a transparent medium for destructive interference between the rays of light which is formed by reflection in the two walls of the  lens. There is less scattering of light
