Standards
 * When electrically charged objects undergo a change in motion, they produce electromagnetic waves around them. 4F/H3a*
 * In empty space, all electromagnetic waves move at the same speed—the "speed of light." 4F/H3c
 * The energy of waves (like any form of energy) can be changed into other forms of energy. 4F/H6c
 * Waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material. All these effects vary with wavelength. 4F/H6ab
 * S11.C.2.1.1 Compare or analyze waves in the electromagnetic spectrum (e.g., ultraviolet, infrared, visible light, X-rays, microwaves) as well as their properties, energy levels, and motion.
 * S11.C.3.1.4 Explain how electricity induces magnetism and how magnetism induces electricity as two aspects of a single electromagnetic force.
 * 3.6.10.B Apply knowledge of information technologies of encoding, transmitting, receiving, storing, retrieving and decoding.
