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?

a. the heavier particles of x-rays indicated by their shorter wavelength enable them to penetrate matter more extensively.
b. the x-rays with their shorter wavelength cause them to be less common
c. the greater energy of x-rays is reflected in their shorter wavelength
d. the higher temperature and increased likelihood of causing burns are associated with the shorter wavelength of x-rays

c. the greater energy of x-rays is reflected in their shorter wavelength

This statement effectively clarifies the distinction between radio waves and x-rays by explaining that x-rays have a greater energy due to their shorter wavelength, which in turn makes them more hazardous compared to radio waves.
