To find the frequency of a radio wave when the wavelength is known, you can use the formula:
Frequency (f) = Speed of Light (c) / Wavelength (λ)
The speed of light is approximately 299,792,458 meters per second (m/s).
Using this formula, if the wavelength of a radio wave is 1 meter, we can calculate its frequency:
f = c / λ = 299,792,458 m/s / 1 meter = 299,792,458 Hz
Therefore, the frequency of the radio wave with a wavelength of 1 meter is approximately 299,792,458 Hz, which is equivalent to 299.8 MHz (megahertz).
