Energy transfer by electromagnetic waves
Did you know?
Electricity can be static, like the energy that can make your hair stand on end. Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic … See more Light is made of discrete packets of energy called photons. Photons carry momentum, have no mass, and travel at the speed of light. All light has both particle-like and … See more One of the physical properties of light is that it can be polarized. Polarization is a measurement of the electromagnetic field's alignment. In … See more The number of crests that pass a given point within one second is described as the frequency of the wave.
