THIS IS AN EXELENTE TUTORIAL
Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
This game focuses on concepts relating to radio frequency modulation.
Identify frequency bands of the electromagnetic spectrum, licensed by the FCC.
