Answer |
| Transparent |
light passes through freely |
| translucent |
light passes through and scatteres (some is absorbed or reflected) |
| opaque |
no light can pass through, all light is absorbed or reflected |
| shadows |
bigger if object is closer to light sorce, smaller if object is farther from light sorce |
| normal |
line drawn at right angle to a soldid barrier |
| incident ray |
incoming light ray |
| reflected ray |
light ray that bounces off |
| angle of incidence |
angle between incident ray and the normal, labelled with an i |
| angle of reflection |
angle bvetween reflected ray and the normal, labelled with an r |
| law of reflection |
the angle of reflection equals the angle of incidence |
| refraction |
bending of a wave when it passes from one medium to another |
| light passing through air to water (refraction)bends ___________the normal |
slows down and bends toward |
| light passing through water to air (refraction) bends ___________ the normal |
speeds up and bends away from |
| angle of refraction |
angle between the refracted ray and the normal, labelled with an R |
| when you look at an object under water, it appears to be _______ where it really is |
above |
| light can also be refracted in air, resulting in _________ |
mirages |
