In the entire Electro-Magnetic spectrum the region for visible light spans most of the total range. True False
White light is made of all colours of the visible spectrum which
has a wavelength range of approximately 380 – 750 nm (violet to
red). White light is incident on a diffraction grating that has 90
lines/mm. What is the width of the 1st order rainbow
band that appears in the diffraction pattern if the screen is 1.60
m away? Express your answer in mm and round to 2 decimal
places.

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?
Calculate the positions of the lines in the hydrogen atom's line spectrum in the visible light wavelength range 400 nm to 700 nm. (Give your answer from the highest wavelength to the lowest with three significant digits.)
