The product of Planck's constant (h) and the velocity of light (c) equals:

12.4 x 10^-7 eVm

The relationship of minimum wavelength to maximum x-ray energy is sometimes called the:

Duane-Hunt law

That region of the x-ray emission spectrum associated with minimum wavelenth is the:

Highest-energy bremsstrahlung x-ray

The wavelength of an x-ray is:

Inversely proportional to its energy

The product of Planck's constant (h) and the velocity of light (c) has units of:

Jm

If one knows the minimum wavelength of an x-ray emission spectrum, one can calculate:

Maximum projectile electron energy

If one knows the minimum wavelength of a given x-ray beam, the kVp of operation can be determined if one also knows:

Planck's constant & The speed of light

How would the total emission spectrum be affected by operation at 80 kVp/400 mA/100ms

Remain the same, but the amplitude would decrease

How would the emission spectrum be affected by the addition of 2 mm Al filtration? The relative position of the spectrum would:

Shift to the right, and the amplitude would be lower

How would the emission spectrum be affected if the power supply were changed from single phase to three phase? The relative position of the spectrum would:

Shift to the right, the amplitude would increase, and the characteristic lines would increase in height

Minimum wavelength is related to :

The kinetic energy of the projectile electron

Which characteristic is reduced as x-ray energy increases?

X-ray wavelength

To calculate minumum x-ray wavelength, one must know the value of:

kVp
