Charging of Insulators
Since charge cannot flow through insulators, neither conduction nor induction can be used to charge, insulators, so in order to charge an insulator friction is used. Whenever an insulator is rubbed against a body exchange of electrons takes place between the two. This results in appearance of equal and opposite charges on the insulator and the other body. Thus the insulator is charged.
For example rubbing of plastic with fur, silk with glass causes charging of these things.

Diffraction of Light
Last modified on:5 years agoReading Time:3Minutes The phenomenon of diffraction was first discovered by Girmaldi. Its experimental study was done by Newton’s and Young. The theoretical explanation was first given by Fresnel. (1) The phenomenon of bending of light around the corners of an obstacle/aperture of the size of the wave length of light is called…
