Question

g's experiment, monochromatic light falls on two narrow slits a distance apart. The experimenter records two consecutive bright fringes at Youn In 0.016.70 and θ 899 but neglects to record the order (rn value). Find the order (m value) of the two fringes A and B a. b. What is wavelength of the light producing the patterm?

Answer 1

let the order corresponding to θΑ-m let the order corresponding to θ B-m + 1 wavelength of the light used λ condition for angular position of mth maxima from the central bright fringe is sin0A -0.1167- d is the spacing between the two slits-d-0.015 mm position of(n +1)th maxima of wave length λ B sin θ A sin θΒ-0. | 547- using e<I in cq^ 0.1547- + -0.1 167 -0.03801 ;d- 0.015 mm > |λ-5.702e-07 m (a) angular postion of mih maxima of wave length λ sin0 0.1167- mA* d- 0.015 mm m- 0.11673.00
