In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 507 nm. An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.32 m and the distance between the two slits is 0.112 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the screen

The path difference is m

Explanation:

Given:

Wavelength of light m

Distance between slit and screen m

Distance between two slit m

Order of interference

From the formula of interference of light,

Where path difference, order of interference

Here we have to find path difference,

 Path difference m

 Path difference m

Therefore, the path difference is m
