100
anything that occupies space and has a shape or form
What is matter ?
100
neutrons and protons
What is the nucleus formed of ?
100
When a neutral atom gains or loses an elctron and becomes an ion
What is ionization
100
equals 1000 volts, measures voltage across x-ray tube
What is kVp
100
one of the most important elements used in the production of x-rays
What is tungsten?
200
Quantity of matter or weight
What is mass?
200
proton
What is part of the atom with positive charge
200
Process of converting alternating current into direct current
What is rectification?
200
equals 0.001 A, measures x-ray tube current
What is mA?
200
The process by which an electric current in one circuit influences a current to flow in a second circuit. Induction occurs because of movement between the magnetic field surrounding wire in the first circuit and coils of wire in the second circuit.
What is electromagnetic induction?
300
building blocks of matter
What is an atom?
300
electrons
What is part of the atom with negative charge
300
transformer with more coils on the primary side
What is a step down transformer?
300
circuit element that increases or decreases voltage by fixed amount
What is a transformer?
300
is approximately 186,000 miles per second
What is the velocity of x-rays ?
400
fundamental particles that compose atoms
What are neutrons, protons and electrons
400
neutrons
What is the part of the atom with no charge
400
transformer with more coils on the secondary side
What is a step up transformer ?
400
allows electrons to flow in only one direction
What is a diode?
400
Solids, liquids, gases
What are the forms of matter?
500
electrons circle the nucleus in these orbits
What are shells?
500
K-shell
What is the most important shell in radiography?
500
form of electromagnetic energy that has no mass, travels in straight line at the speed of light and can penetrate matter
What are x-rays?
500
In US public utilities are delivered at this frequency.
