Web1 de mai. de 2024 · The spectrum of waves is divided into sections based on wavelength. The shortest waves are gamma rays, which have wavelengths of 10e-6 microns or less. The longest waves are radio waves, which have wavelengths of many kilometers. The range of visible consists of the narrow portion of the spectrum, from 0.4 microns (blue) to 0.7 … Webtromagnetic spectrum according to their wave-lengths. (See figure 1.) Radio waves have the longest wavelengths, ranging from a few centime-ters from crest to crest to thousands of kilometers. Micro-waves range from a few centimeters to about 0.1 cm. Infrared radiation falls between 700 nanometers and 0.1 cm. (Nano means one billionth. songs about a mother

Webelectromagnetic spectrum has frequencies between less than 1 billion waves per second (radio) and greater than 3 billion waves per second (gamma rays). Light waves are waves of energy and the amount of energy in a wave is proportional to its frequency. Wavelength increases, while frequency and energy decreases as we go from gamma rays to radio ...
