Understanding the Relationship
* Frequency (f): Measured in Hertz (Hz) and represents the number of cycles per second.
* Wavelength (λ): Measured in meters (m) and represents the distance between two consecutive peaks or troughs of a wave.
* Speed of Light (c): The speed at which electromagnetic waves travel in a vacuum, approximately 3 x 10⁸ meters per second (m/s).
The Formula
The relationship between frequency, wavelength, and the speed of light is:
c = fλ
To find the wavelength (λ), we rearrange the formula:
λ = c / f
Calculation
1. Convert Frequency to Hertz: 300 MHz = 300 x 10⁶ Hz
2. Plug in the values: λ = (3 x 10⁸ m/s) / (300 x 10⁶ Hz)
3. Calculate: λ = 1 meter
Therefore, the wavelength of a 300 MHz signal in free space is 1 meter.
