Skip a page in your CRCT notebook Week 26 1. Matter that takes in light is said to • Reflect it. • Absorb it. • Transmit it. • Use it up.
2. The rough surface of white paper and a smooth white plate are similar because they both • Refract light. • Absorb light. • Diffract light. • Reflect light.
3. The amount of bending of light rays passing through a lens can be controlled by making the sides more or less • Smooth • Opaque • Transparent • Curved
4. A curved piece of glass or other transparent material that is used to refract light is a • Prism • Lens • Mirage • Mirror
5. How is the angle of incidence related to the angle of reflection? • it’s greater. • It’s smaller. • It’s the same. • It’s not focused.
6. Which of the following can be used to magnify an object? • A concave lens • A convex lens • A convex mirror • All of the above
7. How does the lens of the eye focus light on the retina? • It causes light rays entering the eye to spread apart. • It bends light rays entering the eye in a way that brings them together. • It brings light rays entering the eye together and then spreads them apart. • It forces light rays to travel straight through the eye without being refracted.
8. Which of the following BEST describes the image formed on the retina of the eye? • It is smaller than the object being viewed, but it is right-side up. • The image is upside down compared to the actual object being viewed. • The image is much larger than the actual object being viewed. • If the object is close, the image formed is enlarged and right-side up.
9. In an ecosystem, only about 10 percent of the energy in a mouse is passed along to the snake that eats the mouse. What happens to the missing energy? • Some energy is converted into waste heat. • Some energy is used to produce new matter. • Some energy is destroyed in every process. • Some energy is changed into molecules of food.
