Two independent sources………………..produce interference.

Which coherent sources produce fine interference?

Why two independent sources cannot produce sustained interfernce?

Why should we have narrow sources to produce good interference fringes?

Fill ups The sources of light should be preferably……………..for interference.

Two coherent sources whose intensity ratio is 81:1 produce interference fringe. Calculate the ratio of intensity of maximum and minimum in the fringe system.

State with reason, why two independent sources of light cannot be considered on coherent sources.

Which sources produce alternating current?
