Monochromatic light is diffracted by a diffraction grating. By reference to this, explain what is meant by diffraction, coherence, superposition. A parallel beam of red light of wavelength 630 nm is incident normally on a diffraction grating of 450 lines per millimetre. Calculate the number of diffraction orders produced. number of orders = The red light in is replaced with blue light. State and explain the effect on the diffraction pattern.

State what is meant by diffraction and by interference. diffraction: interference: Light from a source S1 is incident on a diffraction grating, as illustrated in . light zero order diffraction grating S1 (not to scale) The light has a single frequency of 7.06 × 1014 Hz. The diffraction grating has 650 lines per millimetre. Calculate the number of orders of diffracted light produced by the grating. Do not include the zero order. Show your working. number = A second source S2 is used in place of S1. The light from S2 has a single frequency lower than that of the light from S1. State and explain whether more orders are seen with the light from S2.

Coherent light passes through a double slit, producing bright and dark fringes on a screen placed parallel to the plane of the double slit. The intensity of the light from each of the slits is initially the same. The intensity of the light passing through one of the slits in the double slit is now increased. The frequency of the light remains constant. What is the effect on the appearance of the fringes on the screen?
