If a wavelength has low frequency, what can be inferred about its number of waves?

A wavelength with low frequency corresponds directly to a lower number of waves per unit of time. Frequency refers to how many waves pass a certain point in a given time frame, usually measured in hertz (Hz), where one hertz represents one wave per second.

When the frequency is low, it means that fewer waves are occurring over that same period. In fact, the relationship between frequency and wavelength is inversely proportional; as frequency decreases, wavelength increases. Therefore, knowing that a low frequency implies a lower number of total waves reinforces the understanding that frequency directly impacts the wave count within a specific timeframe.

This concept is critical in various applications, such as understanding the behavior of electromagnetic waves in different mediums, which is particularly relevant in esthetics when considering the effects of light devices on skin treatments.
