The frequency of a wavelength is the number of wave cycles that pass a fixed point in a given amount of time. It is measured in Hertz (Hz), which represents one cycle per second.

Here's the relationship between frequency and wavelength:

* Frequency (f) and wavelength (λ) are inversely proportional. This means that as frequency increases, wavelength decreases, and vice versa.

* The speed of the wave (v) remains constant.

The formula that connects these three is:

v = f * λ

where:

* v is the speed of the wave (usually the speed of light for electromagnetic waves)

* f is the frequency

* λ is the wavelength

Example:

Let's say a radio wave has a wavelength of 300 meters and travels at the speed of light (approximately 3 x 10^8 m/s). To find the frequency:

1. Rearrange the formula: f = v / λ

2. Substitute the values: f = (3 x 10^8 m/s) / (300 m)

3. Calculate: f = 1 x 10^6 Hz or 1 MHz

Therefore, the frequency of this radio wave is 1 MHz.
