When is interfernce term zero?

When is net force applied zero? Give an example.

What will happen to the interfernce pattern in Young's experiment,if the source is not exactly on the centre line between the slits?

In Young's double slit experiment, the widths of two slits are in the ratio 1:4 . Find at the ratio of maximum and minimum intensity in the interfernce pattern obtained.

In Young's double slit experiment, the widths of two slits are in the ratio 1:4 . Find at the ratio of maximum and minimum intensity in the interfernce pattern obtained.

What should be the width of each slit to obtain 10 maxima of the double slit interfernce pattern ,within the central maximum of teh singel slit diffraction pattern?

In which case interfernce is produced?

The interfernce phenomenon can take place

Show that maximum intensity in interfernce is four times the intensity due to each slit. Hence show that interfernce involves only redistribution of energy.

If the two slits in Young dounle slit experiment have intesity ratio 16:1, Calculate the ratio if intensity at maxima and minima in interfernce pattern,

Write four differences between interfernce nd diffraction.
