Instructions for each slide Slide 1. Open up the Excel file located in the module to fill in the data. Notice the labels for correct insertion. Slide1 - Determine the incident and refracted angles. Calculate the index of refraction for the second medium. Slide1 - Determine the distance of deviation of the incident beam (see lecture for computational part). 4. Slide2 - Determine the apparent depth of the quarter using the index of refraction from slide 1. Label all parts according to lecture sketch. 5. Slide3 - (a) Replace the blue refracted ray with the correct color based on the dispersion model. (b) Determine incident angle and all the angles of refraction. (c) Calculate the index of refraction and speed of light 2.51 units for each color. 6. In the space provided in the spreadsheet, please explain some limitations to (a) accurately determining the index of refraction of unknown slab of material, and (b) investigating and observing the apparent depth of the coin in slide 2. To answer this, get a large bowl of water and place an object at the bottom. Look directly overhead and note your observations for the comment section.
