In a double-slit experiment, green light (5303 ) falls on a double slit having a separation of 19.44 and a width of 4.05 . The number of bright fringes between the first and the second diffraction minima is :
04
10
09
05
Young Double Slit Experiment -
- wherein
Distance of a point on screen from central maxima
Path difference at that point
In YDS For diffraction
For 1st minima
For 2nd minima
Now for Interference .
Path difference at
Path difference at
So order of maxima between A & B
So 5 bright fringes will present between A & B.
