Question: 1 / 400

If a wavelength has low frequency, what is its characteristic?

A low number of waves

When a wavelength has a low frequency, it is characterized by a low number of waves. Frequency refers to how many complete waves pass a given point in a certain amount of time, measured in hertz (Hz). A low frequency means that fewer waves are produced within a second.

In terms of wavelength, low frequency is associated with longer wavelengths. This means that while the number of waves in a given time period is fewer, the distance between each wave is greater. The correct understanding ties the concept of frequency directly to the number of waves present over time, emphasizing that a low frequency reflects a low count of these waves rather than a high one or a short wavelength.

Thus, in the context of the choices provided, the connection between low frequency and low wave count solidifies why this answer is accurate.
