QuestionAnswer
An x-ray photon is a quantum of (Blank) . electromagnetic energy
What is frequency? Frequency is the number of wavelengths that pass a point of observation per second
What is wavelength? The wavelength is the distance from one crest to another, from one valley to another, or from any point on the sine wave to the next corresponding point
What is the wavelength equation? Wavelength = Velocity/Frequency λ = c/f
The electromagnetic spectrum includes the entire range of (blank)? electromagnetic energy
The energy of a photon is (blank) to its frequency. directly proportional
What is the difference between x-rays and gamma rays? The only difference between x-rays and gamma rays is their origin.
Photons interact with matter most easily when the matter is approximately the same size as the photon wavelength.
Visible light behaves like (blank). A wave
What is the inverse square law? I1 is the intensity at distance d1 from the source, and I2 is the intensity at distance d2 from the source.
Kinetic energy Is the energy of motion
Effect of mA and mAs A change in mA or mAs results in a proportional change in the amplitude of the x-ray emission spectrum at all energies.
Effect of kVp A change in kVp affects both the amplitude and the position of the x-ray emission spectrum. In the diagnostic range, a 15% increase in kVp is equivalent to doubling the mAs.
Effect of added filtration The result of added filtration is an increase in the average energy of the x-ray beam with an accompanying reduction in x-ray intensity.
Effect from target material Changing target atomic number is the only factor that will change the discrete x-ray emission spectrum.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
