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 will use the formula for fringe width in Young's double slit experiment and analyze the changes when the screen is moved. ### Given Data: - Change in fringe width (Δβ) = 30 µm = 30 × 10^(-6) m - Distance moved towards the slits (d) = 5 cm = 0.05 m - Distance between the slits (small d) = 1 mm = 1 × 10^(-3) m ### Step-by-Step Solution: ...
