Frequency is the number of cycles or vibrations that occur in one second of a wave. It is measured in Hertz (Hz).
The frequency of a wave is determined by the source of the wave and the medium through which it is traveling. It is not affected by the amplitude or wavelength of the wave.
The wavelength of a wave is inversely proportional to its frequency. This means that as the frequency increases, the wavelength decreases, and vice versa.
Yes, the frequency of a wave can change if the source of the wave changes or if it travels through a different medium. For example, sound waves will have a higher frequency in water than in air.
The frequency of a wave affects its energy and pitch. Higher frequencies have more energy and are perceived as higher pitched, while lower frequencies have less energy and are perceived as lower pitched.
