question 1/10\nx - ray beam quantity refers to the:\naverage energy of the x - ray beam\npenetrating ability of the x - ray beam\nvelocity of photons in the x - ray beam\nnumber of photons in the x - ray beam
Answer
Brief Explanations:
X - ray beam quantity is related to the number of photons in the beam. Average energy refers to quality, penetrating ability is also related to quality, and photon velocity in a vacuum is constant for all electromagnetic radiation including X - rays and is not what quantity refers to.
Answer:
Number of photons in the x - ray beam
