Answer to Question 1

high frequency

Rationale: Shortened wavelengths will be higher frequency, whereas longer wavelengths have lower frequency. The electromagnetic spectrum is arranged by energies from shortest wavelength to longest wavelength.

Answer to Question 2

the lung closest to the image receptor

Rationale: The 45-60 degree posterior oblique position will best image the lung positioned closest to the image receptor.
