Physics 20: Mrs. Tyler Assignment 16 4. Use the following information and diagram to answer parts a and b. A reflecting surface is inclined 30 above the horizontal. A wave is traveling horizontally and reflects off the surface, as shown below. 30 a) What is the angle of incidence? (1) b) What is the angle between the incident ray and the reflected ray? (1) 5. Use the information below to answer parts a-d. In the images below, the reflected wave is darker (in the foreground) and the incident wave is lighter (in the background). The reflecting surface is the bottom of the image. Remember: the ray is perpendicular to the wave. a) In the image above, use a ruler/straight edge to draw: (3) i. A dotted line to represent the position of the normal fi. A dashed arrow to represent the incident ray iii. A solid arrow to represent the reflected ray (1) b) Using a protractor, determine the angles of incidence and reflection.
