Physics 2 Lab Lab 07 3 Part 2: Experiment Part 2.1: Setup 1. Place the basic optics light source flat on the lab table and rotate the knob on the front of the source to produce a single ray of light as shown in the figure to the right. 2. Place the basic optics ray table on the lab bench just in front of the light source with the light ray passing through the center of the ray table. 3. Rotate the top of the optics ray table so that the light ray is aligned with the 0° mark on the table top. This is called the normal line. 4. Place the D-shaped acrylic lens in the center of the table with the frosted side down. Adjust its position so it fits within the lens outline on the tabletop. Part 2.2: Refraction 1. With the equipment setup you should see the light passing through the lens. If you adjust the angle that the light hits the lens, you will see the light change direction due to refraction within the glass. 2. If you look carefully, you’ll notice that the direction of the light ray does not change when it leaves the glass even though ࠵? ! ≠ ࠵? " . Explain why this happens. 3. In the PASCO Capstone software, create Table 1 by using Create User-Entered Data in both columns. Fill in the values shown in the first column.
