A beam of light consisting of two wavelength `650nm` and `520nm` is used to illuminate the slit of a Young's double slit experiment. Then the order of the bright firnge of the longer wavelength that coincide with a bright fringe of the shorter wavelength at the least distance from the central maximum is

A

(a) `1`

B

(b) `2`

C

(c) `3`

D

(d) `4`

Text Solution

Verified by Experts

The correct Answer is:
D
`nbeta_1=(n+1)beta_2`
`implies (nxx650xx10^(-19)D)/(d)=((n+1)xx520xx10^(-19)xxD)/(d)`
`n=4`
