When laser light of wavelength λ falls a metal with 1mm engravings as a grazing angle of incidence, it is diffracted to form a vertical chain of diffracted spots on a screen kept perpendicular to the scale. if the wavelength of the laser is increased by 200 nm. the angle of the first order diffraction changes from 5 degrees to what?

Red light from a laser pointer (lambda = 650 nm) passes through a 0.15-mm slit and lands on a whiteboard 2.5 m from the slit. How wide is the central bright spot?
Q1. (a) Explain how the zeroth-order, first-order, and second-order spectra are produced by the diffraction How many wavelengths are contained in the path- (b) Explain how the different colored spectral lines are formed at higher order and not at zeroth- your reasoning. Note: lasers should NEVER be grating (state the determining conditions).
