The Critical Angle for Total Internal Reflection at a Diamond-Air $\degree$

question 25

Multiple Choice

The critical angle for total internal reflection at a diamond-air interface is 25 $\degree$ . Suppose light is incident at an angle of $\theta$ with the normal. Total internal reflection will occur if the incident medium is:

• A) air and \(\theta\) = 25\(\degree\)
• B) air and \(\theta\) > 25\(\degree\)
• C) air and \(\theta\) < 25\(\degree\)
• D) diamond and \(\theta\) < 25\(\degree\)
• E) diamond and \(\theta\) > 25\(\degree\)

Definitions:

Test Statistic

A calculated value from data that is used to test a hypothesis in the context of statistical analysis, helping determine the probability of observing the given data under the null hypothesis.

Observations

Refers to the individual points or pieces of data collected during a study or research.

Two-Tailed Test

A statistical test that considers the possibility of an effect in two directions, both above and below the mean.

Significance Level

The significance level, often denoted by alpha, is the threshold at which the null hypothesis is rejected in a statistical test.
