Quiz

1. For a wave normally incident from free space onto a planar interface with a perfect conductor, the reflection coefficient is

0

1

-1

Depends on the frequency of the wave



2. The standing wave ratio for perfect transmission (no reflection) is

2

0

1

-1



3. In the most general case, the Fabry-Perot interferometer uses blocks of transparent material of width

Quarter wavelength

Half wavelength

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
