1.
An object that produces its own light.
2.
The bouncing back of light when it strikes a surface.
3.
An imaginary line drawn perpendicular to a reflecting or refracting surface.
4.
Describes an image that cannot be projected onto a screen.
5.
An image that is oriented the same way as the object, not upside-down.
6.
The bending of light due to a change in speed when crossing from one medium to another.
7.
This property of light remains unchanged during refraction.
8.
His law describes the relationship between the angles of incidence and refraction.
9.
The refractive ______ is a measure of how much a material can bend light.
10.
The specific angle of incidence above which total internal reflection occurs.
11.
The "I" in TIR, as the reflection happens inside the optically denser medium.
12.
An optical _____ transmits light and data using total internal reflection.
13.
The outer material of an optical fiber with a lower refractive index.
14.
A lens that converges parallel rays of light; it is thicker at the center.
15.
A lens that diverges parallel rays of light; it is thinner at the center.
16.
An image that is formed where light rays actually converge and can be projected on a screen.
17.
A characteristic of a real image, meaning it is formed upside-down.
18.
The scientific name for short-sightedness.
19.
The splitting of white light into a spectrum of colors.
20.
The band of colors, from red to violet, produced by dispersion.
21.
A transparent optical element, often triangular, used to disperse white light.
22.
Light that consists of only a single frequency or color.
23.
The color of light that slows down the most in a prism and therefore bends the most.
24.
Describes light rays that spread out from a common point
