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?
Q. What is Fresnel diffraction? a) The source as well as the screen are at finite distances from the obstacle producing diffraction. b) The wave front suffer diffraction is

Micro Waves: Micro waves are radio waves with shorter wavelength among 1mm to 300cm. Microwaves are used in Radar and microwave ovens.
Vector Direction The significance of 'direction' could be seen in the dissimilarity among velocity and speed. In physics, speed is a pure scalar or something along with a magni
