Answer:
Radiowaves > microwaves> Infrared radiation > visible light > Ultraviolet radiation > x -rays > gamma rays
Step-by-step explanation:
To solve this problem, we use the electromagnetic spectrum as a reference. On the electromagnetic spectrum, the lesser the wavelength, the higher the frequency and more energetic a wave is.
Therefore;
Radiowaves > microwaves> Infrared radiation > visible light > Ultraviolet radiation > x -rays > gamma rays
So, radiowaves have the longest wavelength and gamma rays have the shortest.
