Q1:

A plane wave having the electric field component V/m and travelling in free space in incident normally on a lossless medium with m = m0 and e = 9e0 which occupies the region y ≥ 0. The reflected magnetic field component is given by

A

B

C

D

ANS:A -

r = - Ve will change direction and M will not change its direction Direction of for incident field is in x, so direction of in the reflected field is also is in x. .
