The higher the frequency the ______ the energy.
higher
lower
neither, stays the same
Answer explanation
The higher the frequency, the higher the energy. This relationship is described by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. Thus, as frequency increases, energy also increases.

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy
Radio waves
Ultraviolet Rays
Gamma Rays
X-rays
Answer explanation
Gamma rays have the shortest wavelength in the electromagnetic spectrum, which corresponds to the highest frequency and most energy. This makes them more energetic than radio waves, ultraviolet rays, and X-rays.
