About this app

Shows what color light will appear based on its wavelength in nm (nanometers) or its frequency, or energy in Hertz, Joules, eV or its wavenumber. Also provides quick unit conversion to all these different units. For any wavelength of light, it will also tell you, roughly, what part of spectrum it is in: UV, IR, Visible, x-ray, gamma-ray, radio etc.

Great for High School, AP, College or University Chemistry, Physics or Biology. Spectroscopist's best mobile tool for laser or incoherent spectroscopy!

Misleading color scheme for wave length in UV and IR and beyond. Otherwise very good reference. Good suggestion to use black color to represent these two extremes.

Very cool, it would be amazing if it had a button for full screen color without text and input box
