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?

what is product of vectors
The experimental set-up for producing Newton's ring is shown in fig. (A). A plane-convex lenses L of large radius of curvature with its convexities is placed on a plane glass plate
how much energy is required to raise an object of 300g that is initially at rest to a height of 2m and simultaneuosly give the object a velocity if 4m/s?
Hertz; Hz (after H. Hertz, 1857-1894) The derived SI unit of frequency, explained as a frequency of 1 cycle per s; therefore it has units of s -1 .
