Electromagnetic waves are categorized in terms of their wavelengths and frequency. This categorization is known as the Electromagnetic Spectrum.
When they are arranged in terms of increasing frequency, their wavelengths are decreasing. This is because wavelength and frequency are inversely proportional.
Since energy and frequency are directly proportional, increasing frequency would mean increasing energy.
In terms of increasing energy, the correct order is:

Answer: The answer is "C"
The electromagnetic waves are arranged in the increasing wavelength and energy by the following order;
Radio waves has the lowest energy and wavelength but of the highest frequency.
The Infra-red rays follows the visible light follows, the ultraviolet ray follows, the X-ray follows and then the Gamma-ray has the highest energy and wavelength but the lowest frequency.
Therefore the answer is C, radio, infra, visible, ultraviolet, x-ray, gamma.
