Write the common properties of eectromagnetic spectrum
Answers
The EM spectrum is the range of all possible frequencies of electromagnetic waves.
At one end of the spectrum are the waves with the lowest frequencies.
At the other end are the highest frequency waves.
The spectrum is broken up into regions that define each of the different wave types.
At the lowest frequencies, we have radio waves. Then, as we increase frequency, we encounter the microwaves, infrared radiation, and visible light waves. Moving further up the spectrum, we have ultraviolet radiation, X-rays, and gamma rays. Gamma rays have the highest frequencies of all the EM waves.
Electromagnetic waves can also be distinguished by their wavelength.
Wavelengths for EM waves can be found by dividing the speed of light by the wave's frequency; this is a modification of the wave equation.
Since all EM waves travel at the speed of light, then the spectrum of wavelengths is exactly opposite the spectrum of frequencies. In other words, wavelength and frequency are inversely proportional to each other.
We can view our electromagnetic spectrum not only in terms of increasing frequencies but also in terms of decreasing wavelengths. As frequencies increase on the EM spectrum, wavelengths decrease
