Electromagnetic Waves in a sentence

Hertz's proof of the existence of airborne electromagnetic waves led to an explosion of experimentation with this new form of electromagnetic radiation, which was called "Hertzian waves" until around 1910 when the term "radio waves" became current.

Radio waves are “non-ionizing radiation” (all electromagnetic waves are referred to as “radiation” in physics); because they occupy the bottom of the electromagnetic energy spectrum, they cannot affect the atoms and molecules in our cells.

A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves.

Electromagnetic waves Ground waves refer to the propagation of radio waves parallel to and adjacent to the surface of the Earth, following the curvature of the Earth.

However, for understanding electromagnetic waves and polarization in particular, it is easiest to just consider coherent plane waves; these are sinusoidal waves of one particular direction (or wavevector ), frequency, phase, and polarization state.

Physically one gets the normal electromagnetic wave solutions to the homogeneous part of the wave equation: : and the inhomogeneous term : acts as a driver/source of the electromagnetic waves.

The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.

The non-ionizing portion of electromagnetic radiation consists of electromagnetic waves that (as individual quanta or particles, see photon ) are not energetic enough to detach electrons from atoms or molecules and hence cause their ionization.

Aether supposedly possessed some wonderful properties: it was sufficiently elastic to support electromagnetic waves, and those waves could interact with matter, yet it offered no resistance to bodies passing through it.

For example, it is commonplace to argue that causal efficacy can be propagated by waves (such as electromagnetic waves) only if they propagate no faster than light.

For transverse waves such as many electromagnetic waves, it describes the orientation of the oscillations in the plane perpendicular to the wave's direction of travel.

If electromagnetic waves traveling through one material meet another material, having a different dielectric constant or diamagnetic constant from the first, the waves will reflect or scatter from the boundary between the materials.

Nearly simultaneous measurements of the electric and magnetic field spectrum allowed electrostatic waves to be distinguished from electromagnetic waves.

While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse in free space.

The pyramidal structures on the walls and ceilings absorb electromagnetic waves, Mojabi said.

Electromagnetic waves enter our eyes, are translated into neural signals, and then flow to the back of the brain, where they’re processed in the visual cortex.

A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect.

There are several variations of electromagnetic waves called a spectrum.

Scientists are searching for enormous absences in the universe, spots in space where gravitational pull is so intense that even light and electromagnetic waves cannot escape.

The wiggling of the light’s electromagnetic waves functions like the pendulum on a grandfather clock, rhythmically keeping time.
