12 Radar works by sending a signal out from an air-traffic control tower that is analyzed by a Doppler scanner on the ground.reflected off a plane back to the control tower.increased in intensity as it passes through the atmosphere.scanned and analyzed by a receiver on board an airplane.
13 The color that an object appears to be depends on the angle at which visible light is reflected off the object.use of additive rather than subtractive colors.wavelengths of visible light that reaches your eyes.speed with which visible light reaches it.
14 When light moves from a material in which its speed is higher to a material in which its speed is lower, it isbent toward the normal.reflected off the boundary.bent away from the normal.changed into a virtual image.
15 Light rays that pass through a lens change direction because of internal reflection.they are refracted.light is broken up into many different colors.virtual images always appear slightly larger than real images.
16 Light demonstrates wave characteristics when it is reflected.diffracted.refracted.All of the above
17 Light demonstrates particle characteristics when it knocks electrons off a metal surface.forms standing waves.passes through a narrow opening.All of the above
18 As the frequency of light waves increases, the energy increases.the energy stays the same.the energy decreases.the wavelength increases.
19 Light rays reflecting off a rough surface reflect diffusely.at all angles.at a single angle.None of the above
20 The law of reflection says the angle of incidence is _____ the angle of reflection. greater thanequal toless thanNone of the above
21 When you look in a convex mirror, the image appears smaller than it really is.larger than it really is.lighter than it really is.darker than it really is.
22 Which statement about a diverging lens is correct? It bends light inward and can create either a virtual or a real image.It bends light inward and can only create a real image.It bends light outward and can create either a virtual or a real image.It bends light outward and can only create a virtual image.
23 Light is composed of waves and particles called: electronsphotonsquarkswaves
24 The visible spectrum of light from the longest to shortest wavelength is: violet, indigo, blue, green, yellow, orange, redred, orange, yellow, green, blue, indigo, violetinfrared, ultraviolet, gamma, x-rays, microwavesgreen, orange, red, violet

27 An example of a diverging lens that spreads light rays is the: convex lensconverging lensconcave lensprism
28 A survivor from a shipwreck sees an image of a fish in the water A survivor from a shipwreck sees an image of a fish in the water. To catch it with her spear, she mustaim above the image of the fishaim at the image of the fishaim below the image of the fishaim behind the fish
