If you could shine a very powerful flashlight beamtoward the Moon, estimate the diameter of the beam whenit reaches the Moon. Assume that the beam leaves theflashlight through a 5.0-cm aperture, that its white light hasan average wavelength of 550 nm, and that the beamspreads due to diffraction only.

Consider a spectrometer based on a diffraction grating. Construct a problem in which you calculate the distance between two wavelengths of electromagnetic radiation in your spectrometer.
