What is diffraction of light? Illustrate a graph showing the variation of intensity with angle in a single slit diffraction experiment. Write single feature which distinguishes the
observed pattern from the double slit interference pattern.
How would the diffraction pattern of a single slit be affected when?
(i) The width of the slit is reduced?
(ii) The monochromatic source of light is changed by a source of white light?

"At base temperature the volume of a gas differs inversely with pressure". If P and V are volume and pressure of a gas at a given temperature then
