Question

which has the shortest wavelength and, therefore, the highest frequency/most energy
ultraviolet rays
gamma rays
x - rays
radio waves

Explanation:

Step1: Recall electromagnetic spectrum properties

In the electromagnetic spectrum, shorter wavelength corresponds to higher frequency and more energy.

Step2: Analyze given options

Gamma rays have the shortest wavelength among ultraviolet rays, gamma rays, X - rays, and radio waves.

Answer:

Gamma Rays
