Which of the following lists contains three regions of the electromagnetic spectrum in order of increasing frequency?
Correct answer: C. Microwaves, ultraviolet rays, X-rays
- A. Gamma rays, ultraviolet rays, radio waves
- B. Gamma rays, visible radiation, ultraviolet rays
- C. Microwaves, ultraviolet rays, X-rays
- D. Radio waves, visible radiation, infrared radiation
Explanation
The electromagnetic spectrum is as such as wavelength decreases frequency increases, therefore the correct answer would be C ,as the question requires in order of increasing frequencies and gamma has the highest frequency, whereas in option D infrared has a higher frequency than ultra violet.
