In a Young's interference experiment, the two slits are separatedby0.13 mm and the incident light includestwo wavelengths:λ1 = 540 nm (green) andλ2 =450 nm (blue). The overlappinginterference patterns are observed ona screen 1.33 m from the slits.
(a) Find a relationship between theordersm1 and m2 thatdetermineswhere a bright fringe of the green light coincides with abrightfringe of the blue light. (The order m1isassociated with λ1, andm2is associated withλ2.)
m2/m1 = 1
(b) Find the minimum values of m1andm2 such that the overlapping of thebrightfringes will occur and find the position of the overlap onthescreen. m1 = 2 m2 = 3 Distance = 4 cm from the central maximum
