You are being asked to determine if there is any oxygen presentin an unknown mixture of gas. You know that when oxygen is made toglow by placing a large potential difference across it, it willproduce light most brightly at the following wavelengths (innanometers): 408, 419, 441, and 465. You use a strong power supplyto make a sample of this gas mixture glow then use a spectroscopeto split the light into its components. The spectroscope containsan interference grating with 500 ± 10 ?????�?.
a. Assuming the mixture does contain oxygen, draw a labeleddiagram showing what the interference pattern produced by thatoxygen would look like.
b. Choose three features of the pattern. Determine the angle(with respect to the center of the pattern) that each of thesefeatures would appear at. For example, you could choose to find theangle for m = 0 for all wavelengths, and m = +1 for the 408 nm and465 nm wavelengths. Or you could determine the angle at 3 differentfeatures – the choice is yours.
