Question

some electromagnetic waves, like x - rays, ultraviolet rays, and gamma rays, are high energy. what does this mean? their frequency is much lower than other electromagnetic waves. their frequency is much higher than other electromagnetic waves.

Explanation:

The energy of electromagnetic waves is directly proportional to their frequency. Higher - frequency waves carry more energy. X - rays, ultraviolet rays, and gamma rays have high frequencies, so they are high - energy waves.

Answer:

Their frequency is much HIGHER than other electromagnetic waves.
