Detailed explanation-1: -Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
Detailed explanation-2: -On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength.
Detailed explanation-3: -Complete step-by-step answer: We know that Frequency is inversely proportional to wavelength, so Red light rays have the lowest frequency and highest wavelength value. This means that Red light rays have the least number of waves in a second than any other radiation.
Detailed explanation-4: -The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light.
Detailed explanation-5: -Radio Waves–The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.
