G482 Physics definitions (all 70 definitions!!!!)

1. lowest frequency in harmonics series where a stationary wave forms (11, 9)
4. the smallest distance between one point on a wave and the identical point on the next wave (i.e. peak to peak) measured in metres (10)
6. a material with low number density of conduction electrons and therefore a high resistance (13)
10. ability of a waves to pass through each other and temporarily occupy the same space and combine then carry on unaffected (13)

2. speed with which energy is transmitted by a wave. v= fλ or c= fλ (4, 5)
3. the energy change of an electron when it moves through a potential difference of 1 volt (12)
5. the addition (superposition) of two or more coherent waves, resulting in a new wave formed (12)
7. work done per unit time (5)
8. an electrical component designed to heat up, melt and break the circuit (hence stop the current) when a specified amount of electrical current passes through it. safety device (4)
9. a quantum packet of energy of electromagnetic radiation (6)
