How is the x-ray beam changed by the addition of one HVL of aluminum?

Explanation:
One HVL of aluminum is defined as the thickness that reduces the beam’s intensity by half. So adding that thickness to the beam halves the transmitted quantity. The energy spectrum does shift toward higher energies a bit because lower-energy photons are attenuated more, but the main observable change described here is a 50% decrease in intensity. The other statements don’t match how HVL works: it doesn’t increase energy by 100%, there is a change in intensity, and it isn’t a 50% increase in quantity.
