Light (or EMR) Wavelength Analyser
Light (or EMR) Wavelength
Enter the light or EMR (Electromagnetic Radiation) wavelength in nanometers to analyse the properties of light (or EMR) at that wavelength and also calculate the frequency.
Human eyesight can see in the range of 380 to 750 nanometers corresponding to the colors of violet to red.
Every wavelength is associated with a particular energy per photon, which this tool also calculates using the Planck relation.
Every temperature produces a particular peak wavelength in the electromagnetic spectrum (along with other frequencies). This tool calculates what temperature would produce that particular peak wavelength (with respect to blackbody radiation) using Wien's displacement law.
