The electromagnetic spectrum categorizes electromagnetic radiation based on its wavelength or frequency. It ranges from long-wavelength, low-frequency radio waves to short-wavelength, high-frequency gamma rays. Visible light, which is the portion of the spectrum that humans can perceive, occupies a sm...
Refraction • Refraction of EMR is dependent on wavelength as can be seen by the prism example below. Source By using a glass prism, white light can be spread by refraction into a spectrum of its composite colours. All wavelengths of EMR can be re- fracted by using the proper mate- ...
