Q21. The diagram below shows a section of a diffraction grating Monochromatic light of wavelength lambda is incident normally on its surface. Light waves diffracted through angle Theta form the second order image after passing through a converging lens (not shown). A, B and C are adjacent slits on the grating. (a) (i) State the phase difference between the waves at A and D. __ (ii)State the path length between C and E in terms of lambda __ Use your results to show that, for the second order image, 2lambda =dsinTheta where dis the distance between adjacent slits.
