Question: 1 / 400

What distinguishes the frequency of gamma rays compared to radio waves?

Gamma rays have lower frequency

Gamma rays have comparable frequency

Gamma rays have higher frequency

Gamma rays are distinguished by having a much higher frequency than radio waves. The electromagnetic spectrum categorizes waves based on their frequency and wavelength, where gamma rays occupy the high-frequency end and radio waves are found at the low-frequency end.

Higher frequency waves, such as gamma rays, carry more energy per photon compared to lower frequency waves, like radio waves. This characteristic energy is important in various applications, including medical imaging and radiation treatment, where gamma rays are utilized. As a result, the significant difference in frequency underlies their distinct properties and applications in technology and science.

Other options do not correctly represent the relationship between gamma rays and radio waves in terms of frequency; thus, they do not accurately reflect the nature of electromagnetic waves.
