From Where does the energy carried by an EM wave come?
The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
How do the types of energy that make up the EM spectrum differ?
Different types of electromagnetic waves have different frequencies; different wavelengths; and different energies per photon.
How do the various types of electromagnetic radiation differ from each other'?
Frequency, wavelength and energy are the only differences. They are all roughly equivalent as well, in that knowing one means knowing the others for EM radiation.

How Does the EM radiation plays significant roles in our life and why?
For example:* We use visible light to see * We use microwave radiation in a microwave oven * We use various types of electromagnetic waves for communication * The Sun's energy comes to us, mainly via EM radiation.
What does electromagnetic have to do with EM radiation?
EM is short for electromagnetic.
What does the earth's atmosphere do to most types of electromagnetic radiation?
It absorbs almost everything except the visible spectrum.
What type of wave is EM radiation?
EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation.

How is EM radiation different from alpha and beta radiation?
EM radiation is essentially high energy light, with wavelengths ranging from 10 nanometers low energy x rays to 10 picometers high energy gamma rays. Beta radiation refers to high speed electrons while an alpha ray is a high speed proton.
At what speed does all EM radiation travel at?
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
What are spectrographs?
Spectrographs are instruments that separate EM radiation (primarily light) into a spectrum of frequencies and record the data. The intensity of radiation at the different frequencies can be used to ascertain information about the source of the radiation or the material through which it is passing.
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
