Across
- 3. the principle that the total electric charge in an isolated system never changes.
- 5. When heated in flames or put in electrical discharges, emit light at well-defined and characteristic frequencies
- 6. The bending of a wave around the edges of an opening or an obstacle
- 9. materials which have a conductivity between conductors (generally metals) and nonconductors or insulators
- 10. The apparent change in frequency caused by either the source of waves moving, the observer moving, or both moving at different velocities
- 13. the rate of flow of electrons in a conductor.
- 16. The property of sound which is used for differentiating between the loud and faint sound
- 18. A capacitor is a device that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated
- 19. refers to the discovery that bodily contact with the Earth's natural electric charge stabilizes the physiology at the deepest levels, reduces inflammation, pain, and stress, improves blood flow, energy, and sleep, and generates greater well-being.
- 22. a substance which does not readily allow the passage of heat or sound.
- 23. the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.
- 24. A unit of frequency (of change in state or cycle in a sound wave, alternating current, or other cyclical waveform) of one cycle per second
- 26. the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.
- 27. A wave generated by a disturbance in electric and magnetic fields
Down
- 1. the study of forces between charges, as described by Coulomb's Law
- 2. demand (an amount) as a price from someone for a service rendered or goods supplied.
- 4. The maximum distance a particle moves from its starting point in a wave
- 7. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.
- 8. Voltage, also known as electric pressure, electric tension, or potential difference, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a test charge between the two points.
- 11. The number of wave cycles to pass a given point per unit of time
- 12. A measure of light power per unit area
- 14. A point on a surface wave where the displacement of the medium is at a maximum
- 15. The wide range of electromagnetic wavelengths
- 17. The angle made by a reflected ray with a perpendicular to the reflecting surface
- 20. The ampere, often shortened to amp, is the unit of electric current in the International System of Units.
- 21. The repulsive or attractive interaction between any two charged bodies
- 25. the action or process of inducting someone to a position or organization.
