The scale of a map is a number of kilometers per centime- ter specifying the distance on the ground that any distance on the map represents. The scale of a spectrum is its disper- sion, a number of nanometers per centimeter, specifying the change in wavelength that a distance across the spectrum represents. You must know the dispersion if you want to com- pare one spectrum with another or make a measurement of, for example, a Doppler shift. Let y represent the position relative to the center of a diffraction pattern projected onto a flat screen at distance L by a diffraction grating with slit spacing d. The dispersion is dA /dy. (a) Prove that the disper- sion is given by L²d dy m(1? + y99/2 (b) A light with a mean wavelength of 550 nm is analyzed with a grating having 8 000 rulings/cm and projected onto a screen 2.40 m away. Calculate the dispersion in first order.
