(a) In Young's double slit experiment, the two slits are illuminated by two different lamps having same wavelength of light. Explain with reason, whether interference pattern will be observed on the screen or not.
(b) Light waves waves from two coherent sources arrive at two points on a screen with path differences of 0 and `lamda//2`. Find the ratio of intensities at the points.

Answer the following: (a) In Young's double slit experiment, the two slits are illuminated by two different lamps having same wavelength of light. Explain with reason, whether interference pattern will be observed on the screen or not. (b) Light waves from two coherent sources arrive at two points on a screen with path differences of 0 and lamda//2 . Find the ratio of intensities at the points.

Light waves from two coherent source arrive at two points on a screen with path difference 0 and lambda//2 . Find the ratio of intensities at the points.

The two slits in Young's double slit experiment are illuminated by two different sodium lamps emitting light of the same wavelength. No interference pattern will be observed on the screen.

The two slits in Young's double slit experiment are illuminated by two different sodium lamps emitting light of the same wavelength. No interference pattern will be observed on the screen.

If Young's double slit experiment, two slits are illuminated by two light sources of the same wavelength, will you observe interference patterns?

A : In Young.s double slit experiment, we observe an interference pattern on the screen if both the slits are illuminated by two bulbs of same power. R : The interference pattern is obserbed only when source are monochromatic.

In Young.s double slit experiment, what is the path difference between the two light waves forming 5th bright band (fringe) on the screen ?
