Answer:
X-rays
Step-by-step explanation:
X-rays from the given choices have the most energy and the highest frequency. Think the spectrum as waves on a beach. If the wave lengths are long (radio waves) the waves would hit you more periodically. If the wave lengths are short (gamma rays) they would hit you a lot more and more constantly causing you to fall over because of how much power they are hitting you at. Gamma rays have the shortest wavelengths, which means they have the most energy and highest frequency, where as radiowaves and long, have low energy and low frequency.
