CLO11: Describe the electromagnetic spectrum.
The entire range of electromagnetic energy grouped together is the electromagnetic spectrum. The basic concept of there being a electric and magnetic field that travels at the speed of light is the same. The only difference is the frequency and wavelength of the various photons. Frequency and wavelength are inversely proportional of each other because the velocity stays constant. The orders of the electromagnetic spectrum goes as follows radio-frequency, microwaves, infrared waves, visible light, ultraviolent light to x-ray and gamma rays.
The electromagnetic spectrum equation states E (energy)=h (plank’s constant)*f (frequency of the photon).
