What is interference of light?

For constructive interfrence to take place between two monochromatic light waves of wavelength lambda ,the path difference should be

What happens to the interference pattern if phase difference between two light sources varies continuously?

In Young's double-slit experiment deduce the condition for constructive and destructive interference at a point on the screen. Draw the graph showing variation of the resultant intensity in the interference pattern against position 'X' on the screen.

When is the interference destructive?

Write the conditions on path difference under which constructive interference occur in Young's double slit experiment.
