PeTA 1 (Physics)

1. is by which light is spread out according to its color as it passes through an object.
5. uses concave lenses and is a single-eyed tool and instrument that can be used to observe distant objects in a small area.
7. an electromagnetic wave that can be detected by the human eye.
10. are lenses that we use and may either use concave or convex lenses depending on the sight of the person.
12. vibrations of light waves occur in a single plane.
13. the term for nearsightedness.
15. uses convex lenses and is an instrument that can be used that makes something appear larger than what they look like.
17. refers to a phenomena that occur when a wave encounters an obstacle or opening.
18. curved pieces of glass or transparent materials that refracts light.
19. the combination of two or more electromagnetic waveforms to form a wave in which the displacement is either reinforced or canceled.

2. is the bending of light as it passes from one transparent substance into another.
3. 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.
4. has a reflecting surface that is curved outward.
6. an image produced by or as a if by a mirror.
8. the term for farsightedness.
9. who stated the Law of Refraction
11. a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy.
14. has a reflecting surface that is curved inward.
15. smooth, shiny surfaces that allows us to see an image or the reflection of their surface
16. uses convex lenses and is an instrument that can be used to observe small objects that is invisible to the human eye.
