Speed of radio waves in meters per second
WebThus 101 MHz is 101 million cycles per second. 7. Radio waves travel at the speed of light, 300,000 km/s. The wavelength of a radio wave received at 100 MHz is a. 0.3 m. b. 3.0 m. c. 30 m. d. 300 m. e. none of these. Reasoning: Use the relationship: wavelength = speed/frequency = 300,000,000 m/s / 100,000,000 = 3 m. 8. WebIn the case of electromagnetic radiation in a vacuum—the speed v is the speed of light, about 3·10⁸ m/s. Thus the wavelength of a 100 MHz FM radio wave is about: 3·10⁸ m/s divided by 10⁸ Hz = 3 meters. For sound waves in air, the speed of sound is 343 m/s. The wavelength of a tuning fork (440 Hz) is thus equal to approximately 0.78 m.
