Off in the distance, you see the headlights of a car, but they are indistinguishable from the single headlight of a motorcycle. Assume the car's headlights are now switched from low beam to high beam so that the light intensity you receive becomes three times greater. What then happens to your ability to resolve the two light sources?

Suppose Young's double-slit experiment is performed in air using red light and then the apparatus is immersed in water. What happens to the interference pattern on the screen?

A wedge containing two glass plates touching at one end and separated at the other end by the wire of diameter $$48\times  10^{-6}m$$  is illuminated normally by light of wavelength $$\lambda $$ = 6400 $$\mathring{A}$$. The length of the wedge $$l $$ is $$12 cm.$$ How many bright images can be seen over this $$12 cm $$ distance?

Find the nature and order of the interference at the point P :

Find the nature and order of the interference at O

Light of wavelength $$500nm$$ goes through a pinhole of $$0.2mm$$ and falls on a wall at a distance of $$2m$$. What is the radius of the central bright spot formed on the wall?
