Question

question 4(multiple choice worth 4 points)
(05.06 lc)
which of the following terms describes the rate at which an action is repeated over time?
frequency
nanometer
trough
wavelength

Explanation:

• Frequency is defined as the number of times an event occurs per unit of time. For example, in the context of waves, it is the number of wave cycles that pass a given point in a specific time interval.
• Nanometer is a unit of length in the metric system, equal to one - billionth of a meter (\(1\times10^{-9}\) meters). It is used to measure very small lengths, such as the wavelength of light in the nanoscale range.
• Trough is the lowest point of a wave. It is a characteristic of a wave's shape, not a measure of how often an action (like wave - oscillation) is repeated.
• Wavelength is the distance between two consecutive points (such as two crests or two troughs) on a wave. It is a measure of distance, not the rate of repetition of an action.

Answer:

Frequency
