As humans, we are most familiar with visible light, a portion of the electromagnetic spectrum associated with light we perceive as colors. To input the frequencies, select teraHertz from the units . The wave with the longest wavelength, radio waves, cannot be seen by the human eye, and therefore doesn't have a color. Discover the basics of fermionic statistics with our Fermi level calculator! [1] Include your email address to get a message when this question is answered. Solvinge for wavelength, velocity or frequency using the following formulas: Calculate Given v and f Calculating wavelength is easy as long as you know the correct equation. Frequency (f) and wavelength () are joined by the equation f = c, where c is the speed of light. Therefore, we can write: In physics and chemistry, we often need to use very small energies to describe phenomena on the atomic scale. Electromagnetic waves are divided up into regions of what is called the electromagnetic spectrum. Please provide feedback on using this Photon Energy to Wavelength Calculator for Electromagnetic Waves in a Vacuum. These wavelengths are absorbed as they have the right amount of energy to excite electrons in the plant's pigments, the first step in photosynthesis.
