To find:
The arrangement of the electromagnetic radiations.
Step-by-step explanation:
The energy of electromagnetic radiation is directly proportional to the frequency of the radiation and inversely proportional to the wavelength.
The energy of electromagnetic radiations is given by,
Where h is Planck's constant, c is the speed of light, ν is the frequency of the radiations and λ is the wavelength.
The radio wave is the electromagnetic wave that has the highest wavelength. The visible light has a wavelength that is less than that of radio waves but greater than that of gamma rays. Gamma rays have the lowest wavelength of all electromagnetic radiations.
Thus the radio waves have the lowest energy. Visible light has energy greater than radio waves. The gamma rays have the highest energy.
Final answer:
The correct order is C, A, B.
Thus the correct answer is option B.
