Young's double slit experiment is carried out by using green, red and blue light, one color at a time. The fringe width recorded are `b_(G)`,`b_(R)` and `b_(B)` respectively. Then,

Options

A. `b_(G)gtb_(B)gtb_(R)`
B. `b_(B)gtb_(G)gtb_(R)`
C. `b_(R)gtb_(B)gtb_(G)`
D. `b_(R)gtb_(G)gtb_(B)`

Answer

D

Explanation

We know that `beta=(lamdaD)/(d)`
Now, `lamda_Rgtlamda_Ggtlamda_B` `:'` `beta_Rgtbeta_Ggt beta_B`
