Problem 15.(adsbygoogle = window.adsbygoogle || []).push({});

By attaching a diffrection-grating spectroscope to an astronomical telescope, one can measure the spectral lines from a star and determine the star's chemicalcomposition. Assume the grating has 3224 slits/cm. The wavelength of the star's light is wavelength 1 = 463.200nm.

find the angle at which the second-order spectral line for wavelength 1 occurs. Answer in units of degrees.
