Across
- 3. The physical laws applying to the microscopic level.
- 4. Any part of reality smaller than an atom.
- 5. The capacity of a physical system to perform work. Energy exists in several forms such as heat, kinetic or mechanical energy.
- 6. Physical objects that are measurable and observable by the naked eye; microscopic being those smaller.
- 8. Packets of energy of a definite size.
- 9. The behaviour of phenomena such as light or other sub-atomic particles.
- 10. A mathematical tool that quantum mechanics uses to describe any physical system.
- 11. Any substance that has mass and occupies space. All physical objects are composed of matter, in the form of atoms, which are in turn composed of protons, neutrons and electrons.
Down
- 1. An experimentally observed phenomenon in which electrons are emitted from metal surfaces when radiation falls on these surfaces.
- 2. Whilst we do not know what the state of any object is, it is actually in all possible states simultaneously as long as we don't look to check.
- 7. As used in physics it is light or energy in the form of waves or particles.
