8. The rainbow of visible colors in the electromagnetic spectrum varies continuously from the longest wavelengths (the reddest colors) to the shortest wavelengths (the deepest violet colors) our eyes can detect. Wavelengths near 655 nm are perceived as red. Those near

515 mm are green and those near 475 nm are blue, Calculate the frequency of li

by of light (in Mz) with a wavelength of 555 nm, 515 nm, and 475 nm.
