Objectives Determine the angle of refraction for a light beam moving from one medium to another. The angle of incidence and each index of refraction can be varied. Using the tools provided, the angle of refraction can be measured, and the wavelength and frequency of the waves in each substance can be compared as well. My hypothesis is that the higher the angle of incidence and index of refraction the wave front will move slower Data Q1: In which image below is the angle of refraction the greatest? A1: Image D Q2: If the angle of incidence increases and the indexes of refraction stay the same, what happens to the angle of refraction? A2: the angle of refraction increases Q3: Based on the image from the Gizmo below, which medium has a larger index of refraction? A3: Medium 1 has a larger index of refraction. Q4: If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of refraction? A4: 32 degrees Q5: A jeweler is determining the optical properties of an unknown blue gemstone. She uses an angle of incidence of 62° and measures an angle of refraction of 30°. Assuming the index of refraction of air is 1.0, what is the index of refraction of the gem?

moves slower. The index of refraction is what slows and speeds up the wave front.
