Final Project in Physics

2. It measures small amount of current.
4. A circuit that contains more then one path for current flow.
9. The man behind the discovery of Ohm’s Law.
12. Is an informed guess about science or scientific relationships.
13. A circuit that contains only one path for current flow.
15. The flow of electric charge.
18. Simplest Form of matter.
21. These reflections build up with each reflection and decay gradually as they are absorbed by the surfaces of objects in the enclosed space.
22. Occurs when a wave hits boundary between two media where the wave speeds differ, but the wave stays in the original medium instead of passing into the second medium
25. The opposition of current flow.
26. Smallest piece of an element containing all of the properties of that element.
27. Is a type of wave in which the medium's vibration is parallel to the direction of the wave, and the medium's displacement is in the same direction as that of the wave movement.

1. A moving wave whose oscillations are perpendicular to the direction of the wave.
3. An instrument used to measure the properties of an electrical circuit.
5. The center portion of an atom.
6. A disturbance in a medium that carries energy without a net movement of particles.
7. The force (pressure) that causes current to flow.
8. The flow of electric charge.
10. Is defined as the characteristic of sound which is used for differentiating between the shrill and flat sound.
11. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.
14. Negatively Charged Particles.
16. The opposition of current flow.
17. It occurs when the size of the aperture or obstacle is of the same order of magnitude as the wavelength of the incident wave.
19. Uncharged atomic particles.
20. Positively Charged atomic particles.
23. Is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time
24. The force (pressure) that causes current to flow.
