Why we use large focal length lens in newton ring?

Answers

Answered by KeshavGiri79

Answer:

In this situation, the air film between the lens and plate will be pretty thin and hence two rays ( one reflected from lower surface of lens and the other reflected from glass plate) will be close to each other so that there will be interference between them.
