The most basic answer is that the electromagnetic spectrum is the range of all the wavelengths (frequencies) of electromagnetic radiations. It basically describes the range of light in our universe.

Visible light is the only part of the EM spectrum we can see, but there are many kinds of invisible light waves. There are seven kinds of wavelengths in the EM spectrum: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma. Radio waves have the lowest frequency, and therefore have the largest wavelengths, which means that gamma rays have the highest frequencies and smallest wavelengths in the electromagnetic spectrum.

Ket [755]

Sensory receptors are found anywhere else in the human body and these receptors help us sense any stimuli from our environment. Within our body, there are thousands of these receptors and these us allow to sense touch, pain, pressure, heat, and cold. These receptors are classified according to complexity. Hope this helps.
