Will there be an interference pattern on...

Will there be an interference pattern on the screen if the slits in Young's experiment are illuminated by two different sodium lamps emitting light of same frequency and wavelength?

Text Solution

Verified by Experts

No, because the phase difference between two lamps will be changing continuously.
