Best Answer

The categories of the electromagnetic (EM) spectrum, in the ascending order of their frequencies are:

  • Radio
  • Microwave
  • Infrared
  • Visible
  • Ultraviolet
  • X-ray
  • Gamma

Hence, Radio waves have the lowest frequency and the longest wavelengths while Gamma rays have the highest frequency and the shortest wavelengths.

Do radio waves have the shortest wavelegnth of all EM waves?

No. In fact, when people try to carve up the EM spectrum into categories and typesand classifications and then name each part, they usually wind up giving the name"radio waves" to the part with the longestwavelengths.


Where is wave located on the em spectrum?

all of the em spectrum is measured i waves


Which of these statements about the EM spectrum is false?

Most of the EM spectrum is visible light.


What are the types of waves in the electromagnetic spectrum?

All electromagnetic (EM) waves are in the EM spectrum. This is from "ELF" (3-30hz) through visible light (300Thz+), out past gamma rays. Any wave above DC that broadcasts into space is part of the EM spectrum.


Why is it true to say that all EM radiation is light even though we can see only a small slice of the spectrum as visible light?

Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.


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?

Name the physical quantity which has the same value for the waves belonging to different em spectrum?

there is no need of medium to travel


Where along the em spectrum does gamma rays fall?

The EM spectrum, is based upon the emission of photons at different wavelengths. Visible light is a small part of this spectrum. As all of the spectrum travels at the speed of light - C. The frequencies for different wavelenghts of photons will be different. The creation of these different parts of the spectrum are from different oscillations (http://en.wikipedia.org/wiki/Electromagnetic_spectrum#Rationale) For instance radio waves come from the oscillation of electrons in an antenna. Limitations on these oscillations cause the limitation in the spectrum, at one end there is radiowaves, limited by electron oscillation and the at the other side is gamma from the creation of particle antiparticle pairs.


How is the EM spectrum applied to science?

EM spectrum involves all radiations of different wavelengths. This has been very useful in studying various things in the field of science. Certain range of wavelengths are also very important in critical analytical techniques.


What to properties of EM waves change from one end of the EM spectrum to the other?

Wavelength and frequency :)


What are the highest-frequency and the lowest-frequency parts of the em spectrum?

-- The lowest frequencies that we have a name for are what we call "radio" waves. -- The highest frequencies that we have a name for are what we call "gamma" rays. Although there is not upper or lower limit in the electromagnetic spectrum.
