In a Young's double slit experiment, a student observes 8 fringes in a certain segment of screen when a monochromatic light of 600 nm wavelength is used. If the wavelength of light is changed to 400 nm, then the number of fringes he would observe in the same region of the screen is
Text Solution
Verified by ExpertsThe correct answer is:
Let length of segment of screen = I
.........(i)
And 
.........(2)
from (1) and (2)
8(600nm)= n(400nm)
n = 12
