Does light have a higher or lower frequency than radio waves?

Does light have a higher or lower frequency than radio waves?

• A. Higher frequency
• B. Lower frequency
• C. About the same
• D. Frequency varies with color

Answer: (A)

Light sits higher in the electromagnetic spectrum than radio waves in frequency, so light has a higher frequency. Radio waves run from a few hertz up to a few hundred gigahertz, while visible light spans roughly 4 × 10^14 to 7 × 10^14 hertz. Because frequency increases across the spectrum, visible light frequencies are far above those of radio waves. Within visible light, color corresponds to specific frequencies (red at the low end, violet at the high end), which helps connect why light’s frequencies are much higher than radio. Therefore, the correct conclusion is that light has a higher frequency than radio waves.
