In the experiment of interfernece, p is the number of bright bands for a light of wavelength `lamda_(1)`. If the source of light is replaced by `lamda_(2)` then the number of bright bands will be

A

`p lambda_(2)//lambda_(1)`

B

`p lambda_(1)//lambda_(2)`

C

`p lambda_(1)`

D

`p lambda_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(1)lambda_(1)=n_(2)lambda_(2)`
`n_(2)=(n_(1)lambda_(1))/(lambda_(2))=(p lambda_(1))/(lambda_(2))`

In a Young's double slit experiment with slit separation 0.1 mm, one observes a bright fringe at angle (1)/(40) rad by using light of wavelength lamda_(1). When the light of wavelength lamda_(2) is used a bright fringe is seen at the same at the same angle in the same set up.
