Lasers are often used in medicine and communication10) bouncing back of a wave after it strikes a barrier11) a picture of an object formed by rays of light13) curved inward Across: 2) the reflection of parallel light rays in many different directions6) technology based on the use of laser light to send signals through transparent wires called optical fibers. This technology is often usede in communications8) reflection of parallel light rays in the same directions12) a law of physics stating that the angle at which light strikes a surface (the angle of incidence) equals the angles at which it reflects off the surface (the angle of reflection)14) a transparent optical tool that refracts light15) a light sensitive membrane at the back of the inside of the eye16) curved outward
