There is a transmission grating, and printed on the frame, you see that there are 500 slits (lines) per millimeter on this grating. The transmission grating is to be illuminated at normal incidence with red light at A = 632.8 nm and blue light at A = 420.0 nm. to) Calculate the distance by which the red light and blue light, in second order (m = 2), are separated on a screen Z =1.0 meters from the grating. You then hold the grating and look through it at a bright point source of white light. (b) find the range of angles for the first order spectrum. You will have to look in that direction to see the colorful spectrum. You can take the visible spectrum to span 380 to 750 nm. m=2 TABLE 32.1 Wavelengths of Visible Light 380450 nm Violet 450495 nm Blue 495470 nm (ircen 570-590 nrn Yellow 5904120 nm Orange 620-750 nm Red
