Instructions Setup the simulation as follows {these should be the default settings). Select the option for Ray in the upper left side of the screen. Select Manual in the lower left side of the screen. Select Air tor the top Material. Select Water for the bottom Material. Drag the Protractor and place it centered on the normal line (perpendicular dashed line) and the boundary:I line between the materials. Your setup should look like the following image. Oh IOU... ilk-CW1\" 1:! :1 ll] A. n e _._I_J 'Om' Oman-I 3; \\9 Part 1 Light Passing from In Less Dense to a Denser medium In this part of the lab, you are going to investigate refraction as light goes from air to water. To this, you are going to adjust the angle of incidence for the incoming light and observe the effect it has on the angle of refraction. To activate the light. click on the red button. To adjust the angle of incidence, put your cursor on the light source and drag it in the direction of the green arrows. For each of the scenarios below, set the angle of incident to the required angle and record the angle of refraction. Use these values. along with the index of refraction for both mediums, to verify Snell's Law for each scenario. Scenario 1: Angle of Incidence Air Index of Refraction n1sin 01 01 n1 30 1.00 Angle of Refraction Water Index of Refraction n2sin 02 zo n2 1.33 Scenario 2: Angle of Incidence Air Index of Refraction n1sin 01 01 n1 60 1.00 Angle of Refraction Water Index of Refraction n2sin 02 02 n2 1.331. In both scenarios, were you able to verify Snell's Law? : 2. Make a general statement comparing the angle of incidence to the angle of refraction as light moves from a less dense to a denser material. : 3. Make a prediction regarding how the angle of incidence would compare to the angle of refraction if the light were moving from a dense to a less dense material. : Part 2 - Light Passing from a Dense to a Less Dense Medium In this part of the lab, you are going to investigate refraction as light goes from water to air. To do this, change Material 1 to Water and change Material 2 to Air. For each of the scenarios below, set the angle of incident to the required angle and record the angle of refraction. Use these values, along with the index of refraction for both mediums, to verify Snell's Law for each scenario. Scenario 1: Angle of Incidence Water Index of Refraction 1.33 Angle of Refraction Air Index of Refraction Scenario 2: Angle of Incidence While: of Refraction 6' 1 450 Angle of Refraction 92 Questions 1. In both scenarios, were you able to verify Snell's Law"? 2. Make a general statement comparing the angle of incidence to the angle of refraction as light moves from a dense material to a less dense material. Does this agree with your prediction in part 1? Lab: THE LAW OF REFRACTION ll 3. Set the angle of incidence to 50. What happens to the refracted ray at this and higher angles of incidence in this scenario? : Part 3 - Solving Problems with Snell's Law In this part of the lab, you are going to calculate the angle of refraction for two different scenarios, then verify the results of your calculation with the simulation. 1. Scenario 1: Material 1 is Air with an index of refraction of 1.00. Material 2 is glass with an index of refraction of 1.50. If the angle of incidence is 45 degrees, calculate the angle of refraction in the space provided below: 2. Setup the simulation to match the parameters of Scenario 1' Make a statement regarding whether or not your calculation agrees with the results of the simulation. : 3. Scenario 2: Material 1 is Glass with an index of reection of 1.50. Material 2 is water with an index of refraction of 1.33. It the angle of incidence is 55 degrees, calculate the angle of refraction in the space provided below: 4. Setup the simulation to match the parameters of Scenario 2. Make a statement regarding whether or not your calculation agrees with the results of the simulation. %
