In a doubIe sIit experiment ,the anguIar width of a fringe is found to be `0.2^(@)` on a screen I m away . the waveIength of Iight used is 600 nm .What will be the anguIar width of the fringe if the entire experiment apparatus is immersed in water? Take refractive index of water to be `(4)/(3)`.

Text Solution

Verified by Experts

Angular width `theta =(lambda)/(d)=0.2^(@)`
When the entire experiment is done under water `lambda'=(lambda)/(u)` and angular width `theta'=(lambda)/(d)=(lambda)/(mud)=(theta)/(mu)=(0.2)/(4//3)=0.15^(@)`
