a. If the fundamental source wave is a vibrating object, what is the fundamental source of an electromagnetic wave ?
b. Give the expression for velocity of E.M waves in vacuum.
c. On what factors does its velocity in vaccum depend ?

Text Solution

Verified by Experts

a. The varying electric and magnetic fields can act as sources of each other and electromagnetic wave is produced.
b. Velocity `=c=(1)/(sqrt(mu_(0)epsilon_(0)))`
Permeability `(mu_(0))` and permittivity `(epsilon_(0))` of free space
