Homework Statement
A plane electromagnetic wave of frequency 5×1014 Hz and amplitude 103 V/m, traveling in a
homogeneous dielectric medium of dielectric constant 1.69, is incident normally at the interface
with a second dielectric medium of dielectric constant 2.25. The ratio of the amplitude of the
transmitted wave to that of the incident wave is ___________.
Homework Equations
The Attempt at a Solution
It should be 1 right? I mean passing from one dielectric medium to another would result in the change of phase velocity but not the amplitude??
