In Young's double slit experiment, the distance between two slits is made three times then the fringe width will become

Options:

Answer:

Solution:

Fringe width, $β = \frac{λ D}{d}$ From question, $d^{'} = 3 d$ $∴$ New fringe width, $β^{'} = \frac{λ D}{d ^{'}}$ $∴ β^{'} = \frac{λ D}{3 d} = \frac{β}{3}$ .
