White coherent light (400 nm- 700 nm) is sent through the slits of a young.s double slit experiment. The separation between the slits is 0.5 mm and the screen is 50 cm away from the slits. There is a hole in the screen at a point 1 mm fromthe centre. In the above problem which wavelength have a strong intensity at the hole? |

Answer» Solution :`y=(xD)/(d) implies 10^(-3) = n LAMBDA(1)/(2)xx(10^3)/(0.5) implies lambda= (1000)/(n)nm` `n=1""lambda 1000nm, ."n=2""lambda= 500 nm` `n=3""333.3nm` `THEREFORE lambda= 500 nm` will have STRONG intensity. |
