Across
- 3. The strength and vitality required to do physical/mental activity
- 5. The number of waves that pass a fixed point in a unit of time
- 7. The range of all types of EM radiation
- 9. Electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye
- 10. A fundamental universal constant that defines the quantum nature of energy and relates the energy of a photon to its frequency.
- 12. light, The portion of the electromagnetic spectrum that can be visible to the naked eye
- 14. A state of a physical system such as an atom or molecule that is highest in energy than the ground state
Down
- 1. Distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
- 2. is a propagating dynamic disturbance of one or more quantities (can be periodic)
- 3. A stable subatomic particle with a negative charge ; found in all atoms (primary carrier of electricity in solids)
- 4. lowest and stable energy state of an atom or particle
- 6. Minimum amount of any physical entity involved in an interaction. Discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents
- 8. Particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
- 11. Periodic variable change in a single period, maximum extent of a vibration or oscillation, measured from the position of a equilibrium
- 13. Surrounds the nucleus of an atom where the electrons are most likely to be at any given time
