  1. 1. Which of the following statements is false? On a new page in your CRCT notebook, label week 27You don’t have to skip a page because you didn’t have a week 26 CRCT quiz • A convex lens refracts light. • A concave lens refracts light. • We see objects because they absorb visible light waves. • We see objects because they reflect visible light waves.

  2. 2. A simple machine cannot • Reduce the amount of work that is done. • Change the direction of a force. • Decrease the input force that is needed. • Increase the distance over which a force is exerted.

  3. 3. What happens to the force of gravity between two objects if the distances between them increase? • The pull of gravity increases. • The pull of gravity decreases. • The pull of gravity stays the same. • The pull of gravity disappears.

  4. 4. An electromagnetic wave is a wave that • Can travel only through matter. • Can travel only through empty space. • Consists of changing electric and magnetic fields. • Is the same as sound waves and water waves.

  5. 5. The amount that light refracts depends on its • wavelength. • amplitude. • intensity. • degree of scattering.

  6. 6. A transparent object that is thinner in the middle than at the edges is a • convex lens • convex mirror • concave lens • concave mirror

  7. 7. A convex mirror and a concave lens both cause light rays to • Slow down. • Spread apart. • Gain energy. • Form blurry images.

  8. 8. What happens when light passes from air into water? • The light speeds up. • The light continues at the same speed. • The light slows down. • The light forms a mirage.

  9. 9. Farsightedness can usually be corrected using • Convex mirrors • Concave mirrors. • Convex lenses. • Concave lenses.

  10. 10. The law of reflections states that the • Angle of incidence is greater than the angle of reflection. • Angle of incidence is less than the angle of reflection. • Angle of incidence is equal to the angle of reflection. • Angle of incidence and the angle of reflection have nothing to do with each other.
