Red light has the lowest frequency of the visible light spectrum, and thus has a longer wavelength. The shortest wavelength of visible light is actually violet, which has a much higher frequency, and why much of the most powerful lasers are violet. If several lasers differing in wavelength, average power and pulse duration can provide comparable acceptable machining quality, 1 micron laser with the longest pulse duration and the higher average power will typically be preferred, as it … di = 29 cm beyond the second lens. Determine the longest wavelength of light required to remove an electron from a sample of potassium metal, if the binding energy for an electron in K is 1.76 × 103 kJ/mol. Check the speed calculator for more information about speed and velocity.. Wavelength (λ) is the distance over which the shape of a wave repeats. 97.26 nm. A micron is defined as one-millionth of a metre. Red light has the longest wavelength and, therefore, the least amount of energy in the visible spectrum. That would show a full second order maximum. Now if you were to take a perament magnet and wave it up and down once per second you would be creating an electromagnetic wave with a freqence of 1 Hz which would have a wavelength of 3X10 8 m. The Extremely Low Frequency band (ELF) 3 - 30 Hz is used to communicate with submarines when they are submerged. Is this the longest lunar eclipse of the century?
