what are the properties and characteristics of electromagnetic waves?

An accelerated charge produces a time-varying magnetic field which in turn produces a time-varying electric field. Thus, electromagnetic wave consists of sinusoidal time-varying electric and magnetic fields and both the fields are perpendicular to each other.

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. ... When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.

Two key points to remember about the characteristics of radiation are that X- and gamma rays are not bits of matter, they are electromagnetic wave forms possessing no charge and no mass, and they can be characterized by frequency, wavelength, and velocity.

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.

electromagnetic waves are a type of mechanical waves, specifically a transverse wave. they transfer energy. electromagnetic waves dont need a medium to travel through but mechanical waves do.

Properties of Waves. There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase.

These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. ... Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

Characteristics Of Electromagnetic Waves An accelerated charge produces a time-varying magnetic field which in turn produces a time-varying electric field. Thus, electromagnetic wave consists of sinusoidal time-varying electric and magnetic fields and both the fields are perpendicular to each other.

This energy is then grouped into categories based on its wavelength into the electromagnetic spectrum. These electric and magnetic waves travel perpendicular to each other and have certain characteristics, including amplitude, wavelength, and frequency.

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. ... All waves can be thought of as a disturbance that transfers energy.

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.

All electromagnetic waves, from radio waves with wavelengths L~km to gamma-rays with L~10e-12 m (i.e. 1 picometre, or 1 pm), are made up of bundles of energy called `photons'. ... So EM radiation can show `classical' wave-like properties in some situations, and `classical' particle-like properties in others.

An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.

One can imagine electromagnetic waves as series of very regular waves that travel at an enormous speed, the speed of light. The frequency simply describes the number of oscillations or cycles per second, while the term wavelength describes the distance between one wave and the next.
