Electrostatic and Energy, Magnetism and Electricity Flashcards
The most dangerous type of light
Ultraviolet
The distance between the individual crest/trough
Wavelength
Rapidity with which the waves hit the shore
AKA The number of waves passing a given point/unit of time
Frequency
Bundle of energy in which how x-rays travel
AKA a quanta
Photon
The time taken to complete one wave; includes a crest and a trough
Period
When did Roentgen discover the x-ray?
November 8, 1895
Concerns the movement of electrons
Due to free electrons
The way radiation is produced in an x-ray tube but on a larger scale
Electrostatics
The intensity of the x-ray beam is inversely proportional to the square of the distance from the source
Most important concept of x-rays
Inverse square Law
Contact electrification
Static electricity
Electricity that occurs when one object is rubbed against another
Friction
Most important of electrification that is used in electronics
Induction
2 conductors
- water
2. copper
3 Insulators
- Rubber
- Plastic
- Glass
1800s Frenchman who developed the amp
Milliamprers
Andre’-Marie Ampere
Regulates the number of electrons used to produce an x-ray
Milliampres
German physicist who discovered resistance and potential difference
George Ohm
The opposite of current flow
resistance
Strength of electron flow
volt
Discovered electromotive force
Alessandro Volta
The force that draws the electrons from an area of excess electrons at one end of a circuit to an area deficient of electrons at the other end of the circuit.
Electromotive force
