The velocity of electromagnetic waves and the velocity of light have value:
Correct answer: B. Same
- A. Different
- B. Same
- C. Opposite
- D. None of these
Explanation
The velocity of electromagnetic waves and the velocity of light in a vacuum have the same value. The speed of light in a vacuum, (c), is the same as the velocity of electromagnetic waves. This unified speed of approximately (299,792,458) meters per second applies to all electromagnetic waves, including visible light, radio waves, microwaves, X-rays, and more.

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.
