Answer:
A 5
Explanation:
The wave with the least amount of wavelength will have the greatest amount of energy.
Wavelength and energy shares an inverse relationship;
E = h f = [tex]\frac{hc}{wavelength}[/tex]
From this equation, we see that the higher the energy of a wave, the lesser its wavelength.
This is why we see that in the electromagnetic spectrum, radio waves have the least energy because they have the longest wavelength.
