Question

22 multiple choice 1 point
will electron energy affect electromagnetic energy wavelength or frequency?
○ wavelength
○ frequency
○ both
○ neither

23 multiple choice 1 point
what is the relationship b/t mas and exposure?
○ directly proportional
○ inversely proportional

Explanation:

Question 22

Electron energy relates to electromagnetic energy via \( E = hf=\frac{hc}{\lambda} \) (Planck's formula). Energy change affects frequency (\( f \)) and wavelength (\( \lambda \)) (since \( c = f\lambda \), constant speed of light). So electron energy affects both.

mAs (milliampere - seconds) determines the number of X - ray photons. Exposure (amount of radiation) increases as mAs increases, following a direct proportion (\( \text{Exposure} \propto \text{mAs} \)).

Answer:

both
