A plane electromagnetic wave in a non-ma...

A plane electromagnetic wave in a non-magnetic dielectric medium is given by `vecE = vecE_(0)(4 xx 10^(-7) x - 50 t)` with distance being in meter and time in seconds. The dielectric constant of the medium is :

A

2.4

B

8.2

C

5.76

D

4.8

Text Solution

Verified by Experts

The correct Answer is:
A
`mu = (C)/(V) = (CK)/(omega) = (3 xx 10^(8) xx 4 xx 10^(-7))/(50) = (120)/(50) = 2.4`
