Mention the conditions to form constructive and destructive interference patterns in Young's experiment related to interence of light.

What do you mean by constructive and destructive interferences ?

wrtie down the conditions for constructive interference.

Write the condition for destructive interference.

Derive an expression for path difference in Young' s double slite experiment and obtain the conditions for constructive and destructive inteference at a point on the screen.

In Young's double slit experiment derive the condition for (i) constructive interference and (ii) destructive interference at a point on the screen.

In what way is dffraction from each slit related to the interference pattern in a double slit experiment?

What is the most important condition for interference of light?

What change will be observed in the interference pattern produced in Young' s double slit experiment, if blue colour of the same intensity is used instead of yellow colour?

If one of tow identical slits producing interference in Young's expeiment is covered with glass, so that the light intensity passing through it is reduced to 50% , find the ratio of the maximum and minimum intensity of the fringe in the interence pattern.
