Which color has the shortest wavelengths?
If a light beam in water strikes the air-water boundary at an angle greater than the critical angle, this occurs. When this happens, all the light waves are reflected.
A lens that is thicker in the center than at the edges. Because convex lenses cause light waves to meet, they are also called converging lenses. The more curved the lens is, the focal length becomes shorter
A transparent object with at least one curved side that causes light to bend.
When all the light waves that strike a boundary between to transparent materials are reflected.
A lens that is thicker in the edges than in the middle. A concave lens is also called a diverging lens. Since it caused light rays to diverge it has no focal point. The image appears upright and smaller than the object.
Surface is curved outward, light waves spread out or diverge, image is always upright, image is always smaller that the object.
Surface is curved inward, light waves come together or converge, image appears to be upside-down if farther from the mirror that focal point, size of the image decreases as the object is moved farther away
Thin, flexible, transparent fibers that act like a like pipe. Total internal reflection makes light transmission in optical fibers possible.
The distance along the optical axis from the center of the mirror to the focal point
A straight line drawn from the center of the mirror.
A mirror that has a surface that is curved outward. Cause light waves to spread out or diverge. You can see a larger area in this mirror
The single point of the optical axis where the the light rays reflect to after striking the mirror.
Has a surface that is curved inward like a spoon. They cause light waves to come together or converge.
Allow only some light to pass through. Objects behind are visible, but not clear.
Materials that do not let any light pass through causing you to not see other objects through them.
The uneven reflection of light waves from a rough surface.
Materials that allow nearly all light that strikes them to pass through. Reflects the least amount of light
How high the wave rises or falls below the rest position
Rhythmic disturbances that carry energy without carrying matter.
