Learners examine how a radiation pyrometer converts the frequency of electromagnetic waves to a temperature reading.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
