Answer to Question 1

sound waves

Rationale: Electromagnetic radiation includes x-rays, gamma rays, radio rays, and light. The major difference between these is their wavelength.

Answer to Question 2

added filtration

Rationale: Added filtration means thin sheets of aluminum are added to the existing inherent filtration. The effect of added filtration is to remove low energies from the beam that contribute to patient skin dose.
