Radio waves can travel 300,000km per second. If someone was dialing from the moon to the earth, a signal would arrive in about 1.3seconds. The distance from the moon to the earth is 390,000km.
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.
Speed, wavelength and frequency.
If u meant radio wave, then velocity of all electromagnetic wave is 3*108 m/s. Hence velocity of radio wave will be the same ,as it as an em wave, irrespective of its wavelength.
Every radio wave has a different length. It depends on the frequency and is inversely proportional to the speed of light. K1ATV, Mesa AZ
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
The wavelength of a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as well as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).
Radar sends out a radio wave and measures the reflected radio wave using it to calculate a target's speed, shape, material the object is made of, and direction of movement.
A radio wave travels at the speed of light in a vacuum, which is approximately 186,282 miles per second (299,792 kilometers per second).
299,792,458 meters per second ( the same speed of light) (Note that the radio wave has no choice of where it's headed, and no choice of its speed. Its speed remains constant as long as it continues moving through the same stuff.)
The speed of every radio wave is 186,282 miles (299,792,458 meters) per second. When you multiply the frequency times the wavelength, that's the result. If it isn't, then you made a mistake somewhere.
The frequency is 1000000000 Hz.
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
