Arrange the following electromagnetic radiations in decreasing order of their frequencies. Gamma rays Ultraviolet rays Radio waves X-rays Select the correct answer from the code given below: Code:

Explanation

The electromagnetic spectrum is arranged in order of decreasing frequency (and increasing wavelength) as follows: Gamma rays → X-rays → Ultraviolet rays → Visible light → Infrared → Microwaves → Radio waves Gamma rays have the highest frequency and energy , used in nuclear and cosmic phenomena. X-rays come next, used in medical imaging.
