Understanding the Relationship
* Frequency (f): Measured in Hertz (Hz), which represents cycles per second.
* Wavelength (λ): Measured in meters, representing the distance between two consecutive peaks of the wave.
* Speed of Light (c): A constant, approximately 3 x 10⁸ meters per second (m/s).
The relationship between these three is:
c = fλ
Calculating the Wavelength
1. Rearrange the equation to solve for wavelength (λ):
λ = c / f
2. Plug in the values:
λ = (3 x 10⁸ m/s) / (70,000 Hz)
3. Calculate:
λ ≈ 4285.7 meters
Therefore, the wavelength of a 70,000 Hz radio wave is approximately 4285.7 meters.
