| photons | small bundles of energy that make up light |
| visible spectrum | small part of the electromagnetic spectrum that you can see |
| electromagnetic spectrum | the entire range of wavelengths from radio waves to gamma rays |
| image | a copy or a likeness |
| plane mirror | a mirror with a flat smooth surface |
| concave mirror | a mirror that is shaped lilke the inside of a spoon |
| convex mirror | a mirror that curve outward like the outside of a spoon and make images look smaller than they really are |
| focal point | where light rays come together at one point |
| refraction | the bending of light waves as they move through different mediums |
| lens | used to bend light |
| nearsighted | can see objects that are close but fare away objects appear blurry |
| farsighted | can see far objects but not objects that are close |
| light waves | do not need a medium to travel through |
| prism | a piece of glass or plastic shaped like a triangle that can separate white light into all of its colors |
| red light | type of light with the least energy and the longest wavelength |
| violet light | type of light with the greatest frequency |
| white light | a micture of all the colors of the visible spectrum |
| x-rays | type of electromagnetic wave with a high frequency and a small wavelength |
| microwaves | type of electromagnetic wave with low energy, low frequency and a large wavelength |
| transverse wave | light is an example of this type of wave in which the wave moves at right angles to the medium |
