3. A spectrometer and diffraction grating are adjusted to view the line spectrum of a source of light. The source emits four wavelengths which are listed in the table below together with the settings of the telescope when it is centred on the first-order diffraction maxima either side of the zero order. Wavelength / nm Telescope setting Telescope setting right 194.4° 196.0° 198.9° 201.6° 448 501 588 668 Source left 165.7° 164.0° 161.1° 158.4° Collimator Slit Telescope 20 8 (degrees) (degrees) Grating (N.B the above diagram shows a single wavelength of the light travelling through the grating) a) Make a table to show the four wavelengths of the light and the corresponding values of 20 and 0, where is the angle between the zero and first order maxima. b) Plot a graph of λ against sin (You can plot this graph by hand or use software) c) Clearly explaining your method, use your graph to determine the grating spacing, d
