Question

obtain the equation for fringe width ​

Answer 1

If the fringe width is 0.75 mm, calculate the wavelength of light. Given: Distance between slits = d = 0.8 mm = 0.8 x 10-3 m = 8 x 10-4 m. Distance between slit and screen = D = 1.2 m, Fringe width = X = 0.75 mm = 0.75 x 10-3 m = 7.5 x 10-4 m. To Find: Wavelength of light used = λ =?

if you are satify with my ans then mark me as a brainlist

if there is something wrong then kindly rectify itm

Answer 2

Distance between slit and screen = D = 1.2 m, Fringe width = X = 0.75 mm = 0.75 x 10-3 m = 7.5 x 10-4 m. To Find: Wavelength of light used = λ =?
