If the number of troughs that pass a point in a given time increases, what has increased? a) wavelength b) frequency c) intensity d) amplitude

Frequency

Explanation:

Wavelength is defined as the distance between two crests or two troughs in a wave. It is measured in meters.

Frequency is defined as the number of oscillations happening in a given amount of time. It is measured in Hertz.

Intensity is defined as the power delivered per unit area.

Amplitude is defined as the maximum displacement of a particle from its rest position. It is also measured in meters.

Hence, if the number of troughs are increasing in a given time, the oscillations increase, the frequency is increased.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
