Problem: A flourescent lamp emits white light composed of 5 colors: blue (at about 440 nm), turquoise (at about 490 nm), yellow (at about 540 nm), orange (at about 585 nm), and red (at about 610 nm). If you wanted to capture the entire first order spectrum of floursecent light on a screen 20 cm behind a 50 slits/m diffraction grating, what is the minimum required width of the screen?
