A physics instructor wants to project a spectrum of visible-light colors from 400 nm to 700 nm as part of a classroom demonstration. She shines a beam of white light through a diffraction grating that has 600 lines per mm, projecting a pattern on a screen 2.9 m behind the grating.

How wide is the spectrum that corresponds to m = 1? Express your answer with the appropriate units.

How much distance separates the end of the m = 1 spectrum and the start of the m = 2 spectrum?

1. Fireflies emit light across the visible spectrum, but the peak intensity of their emission is around a wavelength of 550 nm. So let’s make the approximation that all of the light emitted by a firefly has a wavelength of 550 nm. (a) A typical flash of light from a firefly lasts for about 100 ms and has a power of 1.2 mW. How many photons are emitted in each flash. (b) An “electron volt” (eV) is a unit of...
