ors Physics: Semester 2 Review Name Describe refraction 12. Date Per 13 Define index of refraction (as a ratio) in equation form. 14. A light ray goes from water (n = 1.33) to crown glass (n = 1.52) at an angle of 37 degrees. a. Draw and label a picture of the scenario, including the boundary, normal, incident ray, refracted ray, incident angle, and refracted angle. b. Using your drawing in part (a) as your guide, describe in detail what occurs when light travels from one medium to another. Include in your description information about changes in speed, frequency, and wavelength in the two media. c. Use Snell's Law to calculate the angle of refraction. 15. Describe the two conditions necessary for total internal reflection to occur. Include a statement about the density of the two media. asgenia inlog eviticog out Units 9 & 10: Electrostatics and Current Electricity Essential questions: 1.
