The principle behind the working of cathode ray oscilloscope is which of the following?
Correct answer: D. None of these
- A. Oscillation
- B. Half wave rectification
- C. Full wave rectification
- D. None of these
Explanation
The principle behind the working of a cathode ray oscilloscope (CRO) is the use of a cathode ray tube (CRT) to display electrical signals graphically on a screen. A CRO works by generating a beam of electrons in an electron gun, which is then accelerated towards a fluorescent screen using an electric field.

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.
