X-Ray History
X-rays were discovered by
Who is Wilhelm Conrad Roentgen
It is the smallest particle of a substance
First property
X-rays are created by
What is the conversion of matter into energy
An x-ray photon is
What is a unit of pure energy
X in x-ray means
What is "an unknown quantity"
When electrons are boiled off the cathode of the x-ray tube by heat
What is a thermionic emission
Second property
The production of x-rays depends on
What is the tungsten wire in the negatively charged cathode.
X-rays may be viewed as
What are waves or particles
X-rays are patented?
What is true
The smallest particle of an element
What is an atom
Third property
What is they have no mass
E=MC^2 was created by
Who is Einstein and says anything that has mass can be changed into energy and can be neither created nor destroyed
X-ray photons travel at what speed
What is the speed of light
There are this many known properties of x-rays
What are 12
Atoms consist of
What is a nucleus of protons and neutrons, circled by electrons
Fourth property
E=MC^2 matter to x-rays because
What is, electrons boiled off the cathode in the x-ray tube will be absorbed into whatever they encounter.
Setting the voltage and current on a x-ray generator controls the nature of
What is the quantity and energy of the x-rays produced
The 12 original properties of x-rays have been changed since their initial discovery. True or false?
What is false.
As the number of protons in an atoms nucleus increase, this happens to the electrons
what is they increase as well
Fifth Property
What is they cannot be focused through a lens, they travel through a lens unchanged
The two types of energy used in x-ray technology
What are electrical energy and electromagnetism
Electrical energy applied to an x-ray tube is converted into
What is heat and x-rays
