What does frequency describe? a: distance from crest to crest or from trough to trough on a wave b: depth of a wave c: how often the particles of a medium vibrate d: height of a wave

(C). How often the particles of a medium vibrate.

Further explanation

Let us analyze the answer choices one by one.

A: Distance from crest to crest or from trough to trough on a wave.

This statement represents the definition of wavelength. The distance between crest or between trough is the distance of one wave, that is the wavelength.

B: Depth of a wave.

The depth of a wave is the depth of influence of a water wave, which is about half the wavelength.

C: How often the particles of a medium vibrate.

Yes right, this statement describes frequency. The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium.

D: Height of wave is the distance between two amplitudes.

Recall that the period and the frequency of any wave are inversely related.

Definition:

Amplitude (A) = the maximum displacement from the mean position, in unit of meters (The SI measurement).Period (T) = the time taken for one complete wave (The SI measurement: in second).Frequency (f) = the number of oscillations completed per unit time, or the number of cycles per second (The SI measurement: in Hertz or Hz).Wavelength (λ) = the shortest distance (in meters) along with the wave between two points that are moving exactly in step with one another. In other words, the wavelength is the distance traveled in one wave.Wave speed (v) = the speed (in m/s) at which the wavefronts pass a stationary observer. The speed of the wave is the quotient of wavelength with the period or the product of wavelength with frequency.

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
