Current Attempt in Progress A diffraction grating has 2604 lines per centimeter, and it produces a principal maximum at
\theta =30.2\deg
. The grating is used with light that contains all wavelengths between 410 and 660 nm . What are the two wavelengths of the incident light that could have produced this maximum? Give the longer wavelength as answer (a). (a) Number Units
