The spectrum of a light source has two lines with lB =504nm(blue) and λR = 672 nm (red). This light is used to illuminate a 2-cm long diffraction grating. The first order (m=1) (1)  diffracted blue line is observed at θB =14 . (a) Find the spacing between the rulings of the grating. (b) Specify the diffraction angles of the blue and red lines for the first two orders. (c) How many lines will be observed for each color?
