The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves microwaves infrared waves visible light ultraviolet radiation x rays and gamma rays.

Electromagnetic radiation photons types. Types of ionizing radiation. Like all elementary particles photons are. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.

Some waves are absorbed and others are reflected. Electromagnetic radiation is a form of energy that propagates as both electrical and magnetic waves traveling in packets of energy called photons. Photons are probably best known for.

The electromagnetic spectrum the electromagnetic em spectrum is the range of all types of em radiation. It always moves at the speed of light in a vacuum. There is a spectrum of electromagnetic radiation with variable wavelengths and frequency which in turn imparts different characteristics.

The energy threshold to be considered ionizing radiation is between 10ev and 33ev for photons. Both alpha and beta particles have an electric charge and mass and thus are quite likely to interact with other atoms in their path. All em waves are made up of photons that travel through space until they interact with matter.

The electromagnetic spectrum is the range of frequencies the spectrum of electromagnetic radiation and their respective wavelengths and photon energies. Gamma g radiation consists of photons with a wavelength less than 3x10 11 meters greater than 10 19 hz and 414 kev. Ionizing radiation is radiation that carries sufficient energy to detach electron from atoms or molecules.

Many other kinds of ionizing radiation are made of non em particles. The different types of electromagnetic radiation all of them are light but not quite. The photon is a type of elementary particleit is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves and the force carrier for the electromagnetic force even when static via virtual particlesthe invariant mass of the photon is zero.

Radiation is energy that travels and spreads out as it goes the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The electromagnetic em spectrum encompasses all wave frequencies including radio visible light and x rays. Thus electromagnetic radiation is then grouped into categories based on its wavelength or frequency into the electromagnetic spectrum.

Electromagnetic radiation composed of photons that carry minimum ionization energy or more which includes the entire spectrum with shorter wavelengths is therefore termed ionizing radiation. Gamma radiation emission is a nuclear process that occurs to rid an unstable nucleus of excess energy after most nuclear reactions.
