Honors Physics: Semester 2 Review Name key vocabulary: Date Per 1. Luminous source 2. Illuminated source 4. Diffuse reflection 3. Polarization 5. Specular reflection 7. Refraction . Reflection 8. Index of refraction Practice: 1. List 2 examples each of a luminous source and an illuminate source. a. luminous : b. illuminate: 2. Carson Busses is driving down the road on a sunny day. Reflection of light off the road surface results in a large amount of polarization and a subsequent glare. Annoyed by the glare, Carson pulls out his polarized sunglasses. How must the axes of polarization be oriented in order to block the glare? (Note: the lines on the filters below represent the axis of polarization.) A B C D The Picket Fence Analogy Use the picket-fence analogy to assist you with your answer! 3. Think of a material that reflects almost all the light that shines on it, but in which you cannot see your reflection. Is this diffuse or specular reflection? Explain the difference between diffuse and specular reflection. Describe the images produced by a flat (plane) mirror using the following choices: 4. c. Upright or Inverted? a. Real or Virtual? d. Its location along the principal axis. b. Enlarged or Reduced? A light ray strikes a flat (plane) mirror at 42 degrees. What is the angle of reflection? 5. A concave mirror forms a real image 28 cm away from the mirrored surface. If the object is 13 cm away, what is 6. the focal length of the mirror? If a virtual image is formed 13 cm along the principal axis from a convex mirror with a focal length of -25 cm, 7. what is the object's distance from the mirror? current these resistor, and powant UI
