Write in Short

In a Young’s double slit experiment using light, the apparatus has two slits of unequal widths. When only slit – 1 is open, the maximum observed intensity on the screen is Equation . When only slit – 2 is open, the maximum observed intensity is Equation . When both the slits are open, an interference pattern appears on the screen. The ratio of the intensity of the principal maximum to that of the nearest minimum is Equation .
