Textbook Question
Chapter 33, Problem 46EAP
A chemist identifies compounds by identifying bright lines in their spectra. She does so by healing the compounds until they glow, sending the light through a diffraction grating, and measuring the positions of first-order spectral lines on a detector 15.0 cm behind the grating. Unfortunately, she has lost the card that gives the specifications of the grating. Fortunately, she has a known compound that she can use to calibrate the grating. She heats the known compound, which emits light at a wavelength of 461 nm, and observes a spectral line 9.95 cm from the center of the diffraction pattern. What are the wavelengths emitted by compounds A and B that have spectral lines detected at positions 8.55 cm and 12.15 cm, respectively?

Perry O’tic wanted to look at the atomic emission spectrum of Helium. He created a spectroscope with a diffraction grating (4900 lines per cm) and two metersticks. The diffraction grating was located 23 cm from the optical slit. When Perry O’tic looked through the diffraction grating, he observed a spectral line 8.0 cm from the optical slit. What is the wavelength of the observed spectral line?
Pigments don't survive fossilization; even though we have fossil skin from dinosaurs, we don't know what color they were. But fossilization does preserve structure. Specimens from a rare cache of 50-million-year-old beetle fossils still show the microscopic layers that produced structural colors in the living creatures, and we can deduce the colors from an understanding of thin-film interference. One fossil showed 80 nm plates of fossilized chitin (modern samples have index of refraction n = 1.56) embedded in fossilized tissue (for which we can assume n = 1.33). What is the longest wavelength for which there is constructive interference for reflections from opposite sides of the chitin layers?
