Lenses can never form images that can be captured on a screen. D. There are both converging and diverging lenses. 2. Where would you place an object in front of a converging (convex) lens so that an image of it is never formed? A. Very, very far away from the lens. B. At the focal point of the lens. C. Closer than the focal point of the lens. D. Just a little further away than the focal length of the lens. 3. What is the correct relationship between period and frequency of an oscillation or a wave? A. If period changes, frequency need not change. B. As the period increases, the frequency also increases. C. Period and frequency are inverses of each other. D. The sum of the period and frequency will be a constant. 4. Which of the following is an INCORRECT description of sound? A. Sound is a pressure wave. B. Sound is a transverse wave. C. Sound is a mechanical wave. D. Sound is a longitudinal wave. 5. Which statement about the reflection from plane mirrors is NOT true? A. The reflection does not change the frequency of light. B. Your image is as far behind a mirror as you are in front of it. C. The light rays actually pass through the image. D. Both the object and the image are of the same height. 6. If you hold a white rabbit in white light, it appears white. If you hold it in blue light, it appears blue. If you hold it in green light, it appears green.

C. a wave refracts due to changes in the properties of the medium. D. a wave reflects off a canyon wall and is heard shortly after it is formed.
