**1 Rainbows form because light is being refracted or bent through raindrops which act as a prism.** **2 Light is either reflected, transmitted, or absorbed when it strikes an object.** **3 Transparent = material that transmits most of the light that strikes it** 4 **Translucent = material which scatters light as it passes through** 5 **Opaque = material which reflects or absorbs all of the light that strikes it; the color of an opaque object is the color of light it reflects** 6 **Pigment = colored substances that are used to color other materials; pigments absorb some colors and reflect others** 7 **Reflection = waves bouncing back off a surface through which it cannot pass** 8 **The law of reflection states that the angle of incidence equals the angle of reflection** 9 **Plane mirror = a flat sheet of glass that has a smooth, silver-colored coating on one side; the coating reflects light forming a virtual image** 10 **__Types of mirrors:__** **Convex = surface curves outward** **Concave = surface curves inward** 11 **Refraction = the bending of light waves due to a change in speed** 12 **Lens = a curved piece of glass or other transparent material that refracts light** **13 Convex lens = thicker in the center than at the edges; light rays converge as they pass through** 14 **Concave lens = thinner in the center than at the edges; light rays bend away or diverge** 15 **//__Microscope__// = uses a combination of lenses to form enlarged images of tiny objects**
