In Young's double slit interference experiment, the wavelength of light use

Question

In Young's double slit interference experiment, the wavelength of light used is

6000 ˙ A

. If the path difference between waves reaching a point P on the screen is 1.5 microns, then at that point P

Options:

A . Second maxima occurs

B . Second minima occurs

C . Third minima occurs

D . Third maxima occurs

Answer: Option C
:
C

λ = 6000 ˙ A, x = 1.5 μ m = 15000 ˙ A

For min. (dark band)

x = (2 n - 1) \frac{λ}{2}; 15000 = (2 n - 1) \frac{6000}{2}

15000 = (2 n - 1) 3000

5 + 1 = 2 n

n = \frac{6}{2} n = 3

3rd dark band
