A student learns that radio waves are deemed safe, whereas X-rays are considered hazardous. The student examines the provided electromagnetic spectrum

Given this information, which statement can the student most effectively articulate to clarify the distinction between radio waves and X-rays? (1 point)

A. The greater energy of X-rays is reflected in their shorter wavelength
B. The X-rays with their shorter wavelength cause them to be less common
C. The higher temperature and increased likelihood of causing burns are associated with the shorter wavelength of X-rays
D. The heavier particles of X-rays, indicated by their shorter wavelength, enable them to penetrate matter more extensively.

A. The greater energy of X-rays is reflected in their shorter wavelength
