Which is the shortest electromagnetic wave and carries the largest amount of energy?

sounds like gamma rays

Yes, Gamma rays is probably what they are looking for. There is always a higher frequency than the one you choose :)

The shortest electromagnetic wave on the electromagnetic spectrum is gamma radiation. Gamma rays have the highest frequency and the shortest wavelength among the electromagnetic waves. They are produced by high-energy processes such as nuclear reactions and radioactive decays.

When it comes to carrying the largest amount of energy, it is important to note that the energy of electromagnetic waves is directly proportional to their frequency. Since gamma rays have the highest frequency, they indeed carry the largest amount of energy compared to other electromagnetic waves.

To determine which electromagnetic wave is the shortest and carries the largest amount of energy, you can refer to the electromagnetic spectrum. This spectrum categorizes electromagnetic waves based on their wavelengths or frequencies. Gamma rays are situated at the high-frequency end of the spectrum, indicating their short wavelengths and high energy.
