PLEASE SOLVE THESE AND TYPED THEM ON YOUR COMPUTER. If for some questions you can't draw with your computer, just explain in words what your drawing would look like.

A mask with a single vertical slit is placed between a laser and a screen as shown in the top-view diagram below right. The photograph above the diagram shows the resulting pattern on the screen. H is the distance between the dark spots on either side of the center of the pattern. measured by placing a ruler against the screen. (See the photograph.) is the slit width greater than, less than, or equal to It, the wavelength of the laserlight? Explain yon: reasoning. Pattern on SHOE\" Top-view diagram Single wheel slit in center of mask (not showu) \\,\\ Laser (aimed at slit in mask) In the following questions, consider how a single change to the original apparatus would affect ' the distance H (described above). a. lt'the right half of the slit were covered (so that no light could pass through that side), would the distance H increase. decrease. or stay the some? Explain. b. The pattern at the top of the page was produced by a laser that emits red light. If the laser were replaced by a laser that emits green light (5.2.. light with a shorter wavelength). would the distance H increase, decrease, or stay the same? (The slits are both uncovered.) Explain. _ c. If the screen wan- rmved farther from the slit (using the original laser), would the. distance H increase, decrease, or stay the mine as in the original situation? Explain. d. If the intensity of the (original) laser were increased. would 1h: distance H increase, decrease. or stay themme as in the original situation? Explain
