How do electromagnetic radiations differ?

Answer 1

Electromagnetic radiation is concerned with the movement of photons (individual, discrete 'packets' of light energy.) The frequency of electromagnetic radiation is directly proportional to its energy and inversely proportional to it's wavelength. Thus, a higher frequency will mean that the photons have a shorter wavelength and have more energy.

Different frequencies, and therefore energies, of electromagnetic radiation will give it different properties. Because of this, the frequencies of electromagnetic radiation are divided into a spectrum based on the different properties of electromagnetic radiation of different frequencies. This spectrum goes from radio waves at the very low end to gamma rays at the other end.

See the link at the bottom for a diagram of the Electromagnetic Spectrum.

However, in the below image the word 'heat' is wrong. Between Infra-red and Radio waves are microwaves.

Nuclear radiation is normally concerned with any form of radiation emitted as a result of radioactive decay, in which a large, unstable nucleus of an atom breaks down to form a more stable one.

There are three types of nuclear radiation: alpha, beta, and gamma. Alpha decay is when an unstable nucleus emits an alpha particle which is composed of two protons and two neutrons; i.e. it is effectively a helium nucleus. Beta decay is when an unstable nucleus emits a beta particle (an electron), and gamma emission is when an unstable nucleus emits high energy electromagnetic radiation called gamma rays.

Answer 2

hum are you serious?

• a radiation can be an electromagnetic wave or a particle flux
• the electromagnetic spectrum is an expression which can mean different things: the distribution of wavelengths of an emissive source for example.

another difference is that they don't start with the same letter.

Answer 3

The only difference between electromagnetic radiation is the energy, frequency and wavelength, which are all inter-dependent. the equations for determining these are (light speed/wavelength=frequency),(light speed/frequency=wavelength) and (Energy=Planck's constant*frequency)

Answer 4

EM radiation is a self-propagating, transverse vibration of electic and magnetic fields, that was predicted by Maxwell's Equations to travel at the speed of light. It was soon found that EM radiation and light were the same thing. We now know that EM radiation vary from low frequency, long wavelength (ELF, as low as 3 Hz or 10^8 meters or 10^-15 eV) to high frequency, short wavelength (10^28 Hz or 10^-17 meters or 100 Tev). EM radiation coming from nuclear reactions is commonly referred to as "gamma rays." None of this radiation has any mass.

Particulate radiation is emission of particles with mass: electrons (as in beta decay), neutrons, protons, helium nuclei (ie, apha particles), cosmic rays (very massive particles with near lightspeed velocities from unknown sources outside the solar system), and neutrinos (very light particles produced in beta decay, so light their mass is unknown but larger than zero).

Answer 5

The visible spectrum contains the colors(ROY.G BiV) while the electromagnetic spectrum contains gamma rays, microwve, radio, ultraviolet, infared, and x-ray.

Answer 6

The difference is that in an atomic spectrum, only the radiation of certain wavelengths is emitted. In a continuous spectrum, radiation of all wavelengths is present.
