Atomic and Nuclear Physics with Relativity
Across
- 2. adopted PLank's quantum theory.
- 3. discovered electron.
- 5. first detected the existence of EM waves
- 9. defined absolute motion as the translation of a body from one absolute place to another.
- 12. distance between two points that depends on the observer's frame of reference.
- 14. performed a series of precise experiments confirming the photon theory.
- 16. a theory that compares measurement made by two observer in relative motion to each other.
- 17. Bavarian instrument maker.
- 18. observed that instead of a continous, a series of bright lines is formed.
- 19. his theory of the wave nature of light contributed to the unification of physics.
Down
- 1. a theory that contradicts wave theory.
- 4. observed that zinc plates become positively charged when strucked by light.
- 6. found that a certain substance spontaneously emit charged particle.
- 7. smallest amount of something (elemental unit).
- 8. most intriguing effect of special relativity.
- 10. a theory in which light is made up of very fine particles which are emitted from sources at high temperature.
- 11. energy spent depending on the metallic surface.
- 13. this frequency of incident radiation has the KE of the ejected photon, zero.
- 15. suggested that light can have the dual properties of wave and particle.
- 19. energy equivalence is related to the increase in resistance to change in motion with increasing speed of material bodies.
