Velocity of light is equal to...

Velocity of light is equal to

A

` sqrt ( epsi_(0) mu_(0))`

B

`sqrt(epsi_(0)//mu_(0))`

C

` epsi_(0)// mu_(0)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
Relation for velocity of light ` (c)=sqrt((1)/(epsi_(0)mu_(0)))` ( where ` epsi_(0)=` primittivity constant equal to ` 8.85 xx 10^(-12)F//m and mu_(0)=` permeability constant equal to ` 1.26 xx 10^(-6) H//m` .
Numerically velocity of light (c) `=sqrt((1)/(epsi_(0)mu_(0)))`
`= sqrt((1)/((8.85 xx 10^(-12)) xx (1.26 xx 10^(-6)))) ~~ 3 xx 10^(8) m//s ` .
