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?
When hydrogen atom is excited, it returns to its normal unexcited (or ground state) state by emitting the energy it had absorbed previous. This energy is given out by the atom in t
Q What is Tyndal scattering? Tyndal scattering- When light passes throughout a colloidal solution its path is visible inside the solution. This is for the reason that the
work done by conservative force on a system is equal to
A point charge q is imbedded at the center of a sphere of linear dielectric material (with susceptibility and radiusR). Find the electric field, the polarization, and the bound cha
