In this animated object, learners examine how magnetic waves are transmitted as radio signals.

In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.

In this learning activity you'll explore how to reduce electromagnetic interference (EMI) and crosstalk between adjacent wires.

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

Learners consider the most common types of electromagnetic waves and the kinds of hardware used in a wireless network. A short quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
