Reflection and Transmission Coefficients

Front

What is the reflection coefficient defined as?

Back

The ratio of reflected intensity to incident intensity

Front

What primarily causes reflection of light at the boundary between two transparent media?

Back

Difference in optical impedance (or refractive index)

Front

True or False: The transmission coefficient represents the fraction of incident light intensity that passes into the second medium.

Back

True

Front

True or False: For a lossless interface, the sum of the reflection coefficient and transmission coefficient is equal to 1.

Back

True

Front

Match the term 'Reflection coefficient' with its description.

Back

Ratio of reflected intensity to incident intensity

Front

Match the term 'Transmission coefficient' with its description.

Back

Ratio of transmitted intensity to incident intensity

Front

Match the term 'Normal incidence' with its description.

Back

Light strikes the surface perpendicular to the boundary

Front

If the reflection coefficient at an interface is 0.25, what fraction of the incident light intensity is reflected?

Back

0.25 (or 25%)

Front

At normal incidence, reflection and transmission coefficients depend mainly on what?

Back

Refractive indices of the two media
