PLEASE ANSWER

Order the types of electromagnetic waves from most to least energy.

Radio waves <  Micro waves < Infrared rays < Visible light < Ultraviolet rays < X-rays < Gamma rays  

Explanation:

Electromagnetic radiation gives an extensive range of regularities and wavelengths. This distinct range is known as the electromagnetic spectrum. The Electromagnetic spectrum is commonly classified into 7 prominent regions, in the order of increasing wavelength and decreasing energy and particular frequency. The common divisions are radio waves() < microwaves() < infrared rays (IR)() <visible light (VIBGYOR) () < ultraviolet rays (UV)() < X-rays() < Gamma rays().

The visible light is the only region between infrared rays and ultraviolet rays which can be seen by our eye. It makes up only small part of the radiation. The visible light consists of 7 prominent colors namely Violet(least wavelength, high frequency) to Red(more wavelength, low frequency) intermediate colors are Indigo,Blue,Green,Yellow,Orange.

The wavelengths of these colors range from 400 - 700 nm
