Problem
In a YDSE, the wavelength of light is 600 nm with an experimental uncertainty of 1 %. The screen is 1.5 m from the slits with an uncertainty of 0.5 %, and the slit separation is 0.25 mm measured with an uncertainty of 2 %. Calculate the percentage uncertainty in the value of the fringe width obtained from these measurements.
