A1) A light of wavelength (460 nm) falls on a pair of slits separated by 0.2mm. i) Calculate the phase difference between a wave impacting the central maximum and another at 0.8 cm from central maximum. The distance between the slits and the screen is 1.2m. Show all results. ii) Calculate the intensity of strip i) with respect to the intensity of the central maximum. Show all results. iii) Calculate the order (m) of the strip in i). Show all results.
