Select the arrangement of electromagnetic radiation which starts with the lowest energy and increases to greatest energy?

Correct answer: D. radio, infrared, visible, ultraviolet, x-ray, gamma ray

  • A. radio, visible, infrared, ultraviolet, x-ray, gamma ray
  • B. radio, infrared, visible, x-ray, gamma ray, ultraviolet
  • C. visible, radio, infrared, ultraviolet, x-ray, gamma ray
  • D. radio, infrared, visible, ultraviolet, x-ray, gamma ray

Explanation

Energy increases with frequency and decreases with wavelength: radio, infrared, visible, ultraviolet, X-rays, then gamma rays. Therefore option d gives the correct low-to-high energy order.
