A) increases
B) decreases
C) remains unchanged
D) none of the above
Correct Answer: C
Solution :
Distance between two adjacent bright (or dark) fringes is called the fringe width. It is denoted by\[\beta ,\] thus, \[\beta =\frac{D\lambda }{d}\] where D is the distance between slit source and screen and d is separation of slits. Since, D and d are increased to same extent, so fringe width (w) will remain unchanged.You need to login to perform this action.
