11 Ιαν 2024 · period (or frequency) – The period of the wave is determined by how long it takes the wave's generator to complete a full cycle. The wave's frequency will exactly mimic the frequency at which it is driven. wavelength – The length of a wave is determined by a combination of its frequency and wave speed.
A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time. A wave with a larger frequency has more energy. If a wave’s frequency doubles, its energy also doubles. A wave’s energy is proportional to the square of its amplitude.
28 Δεκ 2020 · The frequency of a wave, f , is a measure of how many waves pass by, or how many oscillations occur, in one second. The SI unit of frequency is hertz (Hz).
11 Ιαν 2023 · To a good approximation \(v_{\text{wave}}\) depends only on properties of the medium, not on wave amplitude or frequency. For large waves, or for waves with extreme frequencies, this approximation breaks down.
A wave can vibrate back and forth very frequently, yet have a small speed; and a wave can vibrate back and forth with a low frequency, yet have a high speed. Frequency and speed are distinctly different quantities. Wave speed will be discussed in more detail later in this lesson.
An alternative way of measuring the temporal feature of the wave is the rate at which medium displacements repeat, called frequency. Frequency is measured in units of cycles per second, a unit known as hertz ( Hz ).
