1. vibrations of light waves occur in a single plane.
4. a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy.
5. the combination of two or more electromagnetic waveforms to form a wave in which the displacement is either reinforced or canceled.
6. is by which light is spread out according to its color as it passes through an object.
8. uses concave lenses and is a two-eyed tool and instrument that can be used to observe distant objects with a wider field of view.
