0
1
-1
Depends on the frequency of the wave

Multiple quarter-wavelengths
Multiple half wavelengths
4. If a wave is incident onto an interface at the Brewster's angle
It is completely transmitted
It is completely reflected
It suffers total internal reflection
The reflection coefficient is -1
5. If a Gaussian pulse is propagated through a lossless but dispersive channel
The pulse broadens out
The pulse increases in amplitude
The pulse remains constant in amplitude
The pulse becomes narrower
