1 Exam Name MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) Is it possible to see a virtual image? A) No, since the rays that seem to emanate from a virtual image do not in fact emanate from the image. B) Yes, but only indirectly in the sense that if the virtual image is formed on a sheet of photographic film, one could later look at the picture formed. C) Yes, since almost everything we see is virtual because most things do not themselves give off light, but only reflect light coming from some other source. D) Yes, the rays that appear to emanate from a virtual image can be focused on the retina just like those from an illuminated object. E) No, since virtual images do not really exist. 2) A spherical mirror on which reflection takes place on the outer surface of the spherical shape is referred to as a A) concave mirror. B) convex mirror. 3) A spherical mirror on which reflection takes place on the inner surface of the sphere is referred to as a A) concave mirror. B) convex mirror. 4) If the radius of curvature of the concave mirror is r, the focal length is A) r/2. B) r. C) 2r. D) cannot be determined from the information given 5) A light ray, traveling parallel to a concave mirror's axis, strikes the mirror's surface near its midpoint. After reflection, this ray A) passes through the mirror's focal point. B) passes through the mirror's center of curvature. C) again travels parallel to the mirror's axis. D) travels at right angles to the mirror's axis. 6) Light arriving at a concave mirror on a path through the center of curvature is reflected A) through the focal point. B) back parallel to the axis. C) back on itself. D) midway between the focal point and the center of curvature. 1) 2) 3) 4) 5) 6) 1
2 7) A light ray, traveling obliquely to a concave mirror's surface, crosses the axis at the mirror's focal point before striking the mirror's surface. After reflection, this ray A) travels at right angles to the mirror's axis. B) travels parallel to the mirror's axis. C) passes through the mirror's center of curvature. D) passes through the mirror's focal point. 8) Light arriving at a concave mirror on a path through the focal point is reflected A) through the focal point. B) back on itself.

Write your answer in the space provided or on a separate sheet of paper. 9) State how to draw the three rays for finding the image position due to a curved mirror. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 10) If you stand in front of a concave mirror, exactly at its focal point, A) you will see your image and you will appear larger.

If you look at the bottom (convex) side of a shiny spoon, what will you see? A) You will see a little you, but whether you are right side up or upside down depends on how near you are to the spoon. B) You will see a little you, right side up. C) You will see a little you, upside down. D) You won't see an image of yourself because no image will be formed.
