Number OF Maximum on Screen Variation OF Intensity

Youngs Double slit experiment | variation of intensity on screen

In Young's double slit experiment, phase difference between the waves at a point on screen having intensity less than the average intensity on screen may be

In a YDSE experiment, d = 1mm, lambda = 6000Å and D= 1m. The minimum distance between two points on screen having 75% intensity of the maximum intensity will be

In YDSE, D = 1.2m and d= 0.25cm, the slits are illuminated with coherent 600nm light. Calculate the distance y above the central maximum for which the average intensity on the screen is 75% of the maximum.

Many animals use the diurnal and seasonal variations in light intensity and photoperiod to time their
