![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?](http://img.homeworklib.com/questions/99d3c0c0-ce44-11ea-9ccb-3d354da70e2a.png?x-oss-process=image/resize,w_560)

A) Visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. It range from
wavelength- 390 to 700 nm.
frequency- 430 to 770 THz.
B) Yes, secondary colours can be created by these primary colours which are R- red, G-Green, B-blue by mixing these in different proportion.

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 nm are green and those near 475 nm are blue. Calculate the frequency of light (in Hz) with a wavelength of 655 nm, 515 nm, and 475 nm. 655 nm: 515 nm: 475 nm:

The photoreceptors in the human eye, called rods and cones, have different sensitivities to different wavelengths of electromagnetic waves. (Figure 1) (Notice that the y axis in the figure is a logarithmic scale.) The rods, which number over 100 million, can only be activated by a certain range of wavelengths, but they do not pass any color information to the brain. In other words, they note differences in shades of grey (from black to white) and are responsible for a...
