1} [shuttlation] Open the simulation: httpst'pheLcolorado.edui'simsu'htmlt'waveinterferenceflatestu'wave-interference_en.html Click on \"Slits\" Set the following settings: o select laser {the rightmost picture} select 2 slits set the slit width to minimum (Entinn move the slits as close as possible to the laser click on "screw" and \"intensity\" a] Run the simulation and watch the bright spots projected onto the screen as depicted on the intensity plot Take a screenshot of the simulation and include in your FNT submission. b] Use the tape measure to measure everything you need in order to calculate the slit separation {refer to the equation you derived in Activity 5.14}. Describe how you did all of your measurements. c} Calculate the slit separation using your measurements in b} and compare to the set slit separation. if there is a difference between the two numbers, explain why that might be. Think back the derivation of the equation. d] Predict what will happen to the distance between the bright fringes when you change the light to blue color. Explain your prediction and tun the simulation by changing the color of the laser to blue. if the result is different from what you predicted, explain why. I} (challenge) 1it"ou are performing a double slit experiment very similar to the one from DL by shining a laser on two narrow slits spaced T25 x it] '5 meters apart. However, by placing a piece of tnystal in one of the slits, you are able to make it so that the rays of light that travel through the two slits are it out of phase with each other (that is to say, of\". = 51-]. if you observe that on a screen placed 4 meters from the two slits that the distance between the bright spot closest to the center of the interference pattern and the center of the pattern is 1.5 cm, what is the wavelength of the laser\"? (Just as in DL, you may use the small angle approximation gin El so tan 9 x 9 .} 3} [application] Find a room that is dark except for one light source {don't foe-k at the sun} and look through your diffraction grating at that light source. Then move the grating closer to your eye until you see colored light through the grating. Explain why you see different colors at various angles when the light straight through is white. Why is blue closest to the center
