The field produces electromagnetic waves when an accelerating field is applied to a _:
Correct answer: B. Charge
- A. Magnetic field
- B. Charge
- C. Direction
- D. None of these
Explanation
An accelerating charged particle produces an electromagnetic (EM) wave. Electromagnetic waves are electric and magnetic fields traveling through empty space with the speed of light c. A charged particle oscillating about an equilibrium position is an accelerating charged particle. A charge falling in an electric field is accelerated by the electric force and thus produces EMWs. An electromagnetic wave can be created by accelerating charge. An accelerating charged particle produces an electromagnetic (EM) wave.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
