Set 18 Problem 1 Monochromatic light of wavelength 668 nm falls on a slit. If the angle between the first bright fringes on either side
Set 18 Problem 1 Monochromatic light of wavelength 668 nm falls on a slit. If the angle between the first bright fringes on either side of the central maximum is 31 , estimate the slit width a. VO a = m abc sin(x) Ox10 Submit Reset Reset All As an estimate, assume the first bright fringe is halfway between the first and second minima. Note that 31 . is the angle between the first bright fringes on either side of the central maximum, not the angle between the first bright fringe and the center of the diffraction pattern
