FINAL PROJECT IN PHYSICS II

2. It occurs when the size of the aperture or obstacle is of the same order of magnitude as the wavelength of the incident wave.
8. A circuit that contains more then one path for current flow.
10. 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
12. A moving wave whose oscillations are perpendicular to the direction of the wave.
14. Phenomenon can occur with light, but not with sound?
17. 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
19. The flow of electric charge.
20. Uncharged atomic particles.
24. These reflections build up with each reflection and decay gradually as they are absorbed by the surfaces of objects in the enclosed space.
25. Simplest Form of matter.

1. The SI unit of potential difference.
3. The center portion of an atom.
4. Negatively Charged Particles.
5. The force (pressure) that causes current to flow.
6. Positively Charged atomic particles.
7. Is an informed guess about science or scientific relationships.
9. An instrument used to measure the properties of an electrical circuit.
11. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.
13. Smallest piece of an element containing all of the properties of that element.
15. The opposition of current flow.
16. 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.
18. A disturbance in a medium that carries energy without a net movement of particles.
21. It measures small amount of current.
22. A circuit that contains only one path for current flow.
23. Is defined as the characteristic of sound which is used for differentiating between the shrill and flat sound.
