Alchen [17]

The correct answer is C. microwaves, infrared, visible, gamma rays

Electromagnetic waves arranged in order of  frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.

Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.

According to the Einsteins equation, E=hf, Energy is  directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
