In young's double slit experiment with monochromic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 cm towards the slits, then the change in fringe width is `30mum` if the distance between the slits is 1mm, then calculate wavelength of the light used.

To solve the problem, we need to calculate the wavelength of the light used in Young's double slit experiment based on the provided information. ### Step-by-Step Solution: 1. **Understand the Given Information**: - Change in fringe width (Δβ) = 30 µm = 30 x 10^(-6) m - Distance between the slits (d) = 1 mm = 1 x 10^(-3) m - Initial distance from the slits to the screen (D_initial) = 5 cm = 5 x 10^(-2) m ...
