Q1:

Electromagnetic radiations propagate in vacuum with a velocity of __________ metre/second.

A 3 x l05

B 3 x l08

C 3 x l010

D 3 x l012

ANS:B - 3 x l08

Electromagnetic radiations, including light and other forms of electromagnetic waves, propagate in vacuum at the speed of light, which is approximately 3×1083×108 meters per second (300,000,000300,000,000 meters per second). This value is commonly denoted by the symbol c in physics equations.
