Chapter–9: Ray Optics and Optical Instruments Case Study 1: Read the following paragraph and answer the question The lens Maker’s formula is usefull to design lenses of desired focal lengths using surfaces of suitable radii of curvature. The focal length also depends on the refractive index of the material of the lensand the surrounding medium. … Read more

An oscillating charge is an example of accelerating charge

Chapter 8: Electromagnetic waves Oscillating Electric Field An oscillating charge is an example of accelerating charge. It produces an oscillating  electric field in space, which produces an oscillating magnetic field, which in turn produces an oscillating electric fields and so on. The oscillating electric and magnetic fields regenrate each other as a wave which propagetes … Read more

A capacitor is a system of two conductors separated

Case Study Chapter 2 Electrostatic Potential and Capacitance : A capacitor is a system of two conductors separated by an insulator. The two conductors have equal and opposite charges with a potential difference between them. The capacitance of a capacitor depends on the geometrical configuration(shape, size and separation) of the system and also on the … Read more
