High-frequency electromagnetic waves with short wavelengths include which type?

• A. Radio Waves
• B. Infrared
• C. X-Rays
• D. Visible Light

Answer: (C)

High-frequency waves have very short wavelengths in the electromagnetic spectrum, and they carry more energy per photon. Since the speed of light is the same for all these waves in vacuum, frequency and wavelength are inversely related: f = c/λ. So shorter wavelengths mean higher frequency and energy. Among the options, radio waves have long wavelengths and low frequency, infrared has shorter wavelengths than radio, and visible light is short but not as short as X-rays. X-rays have the shortest wavelengths in this set, corresponding to the highest frequency and energy, making them the correct type. (Ultraviolet and gamma rays are also high-frequency, but they’re not listed here.)
