what does the electromagnetic spectrum show
The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes  the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.he image below shows where you might encounter each portion of the EM spectrum in your day-to-day life. The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom).
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm.In terms of frequency, this corresponds to a band in the vicinity of 430â770 THz.he visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.
