A thin beam of light of wavelength 50 μm (in the infrared portion of the em spectrum) goes through a thin slit and falls on a screen 3.00 m past the slit. You observe that the first completely dark fringes

occur on the screen at distances of ±8.24 mm from the central bright fringe, and that the central bright

fringe has an intensity of I0 at its center. (a) How wide is the slit? (b) What is the highest order fringe

this scenario is capable of producing? (c) What is the intensity of light at a point on the screen that is

one-quarter of the way from the central bright fringe to the first dark fringe?

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no
