If something fluoresces the color green when hit with LED light. at what wavelengths absorbed does it fluoresce?
Homework Answers
When the sample is excited with 405 nm light (violet), it fluoresces at 512 nm (green). This change in wavelengths, referred to as the Stokes shift, is due to energy loss between the absorbed and emitted photons (quanta of light).
If something fluoresces the color green when hit with LED light. at 405 nm wavelengths absorbed it fluoresce.

10 pts] (a) What is the range of the visible spectrum in terms of wavelengths and frequencies? b) Most TVs, computer monitors, LED displays, and other color output devices use the RGB color model, in which colors are made by combining red, green, and blue in different intensities. Can any other color (including white light, the combination of all colors) be created by these RGB displays with the same maximum intensity as with these colors? Why or why not?
