The frequency of a wave is the number of complete cycles of the wave that occur in a given unit of time. It is measured in hertz (Hz), which is equal to one cycle per second. The amplitude of a wave is the maximum displacement of a point on the wave from its rest position. It is a measure of the intensity or strength of the wave.
The relationship between frequency and amplitude in a wave is that they are independent of each other. The frequency of a wave determines the pitch of a sound wave or the color of a light wave, while the amplitude determines the loudness of a sound wave or the brightness of a light wave. In other words, frequency and amplitude are two separate properties of a wave that do not directly affect each other.

Wave: A disturbance that travels through a medium, transferring energy without transporting matter.
Frequency: The number of cycles or oscillations of a wave passing through a given point in a given amount of time. It is measured in Hertz (Hz), which represents cycles per second.
Amplitude: The maximum displacement of a wave from its equilibrium position. It represents the intensity or strength of the wave.
Relationship:
The frequency, wavelength, and amplitude of a wave are related as follows:
- Frequency (f) is inversely proportional to wavelength (λ): f = 1/λ - Amplitude (A) is directly proportional to the square root of the energy (E) of the wave: A ∝ √E
These relationships can be seen in the following equation:
``` v = fλ ```
where:
- v is the wave velocity - f is the frequency - λ is the wavelength
Example:
Imagine a water wave with a wavelength of 1 meter (λ = 1 m) and a frequency of 2 Hz (f = 2 Hz). This means that the wave travels 2 meters (2λ) per second (v = 2 m/s). If the wave has an amplitude of 0.5 meters (A = 0.5 m), it means that the water molecules at the crest and trough of the wave are displaced 0.5 meters from their equilibrium position.
