Light is an electromagnetic wave. Its speed in vacuum is given by the expression

A

`sqrt(mu_(0)epsilon_(0))`

B

`sqrt((mu_(0))/(epsilon_(0))`

C

`sqrt((epsilon_(0))/(mu_(0))`

D

`(1)/(sqrt(mu_(0)epsilon_(0)))`

Text Solution

Verified by Experts

The correct Answer is:
D
`c= (1)/(sqrt(mu_(0)epsilon_(0)))= (1)/(sqrt(4pi xx 10^(-7) xx 8.85 xx 10^(-12))) ~~ 3 xx 10^(8) m//s`
