Question

What can be found by counting the number of troughs per second in a wave diagram? A)amplitude B)direction C)frequency D)speed E)wavelength?

Answer 1

The correct answer is C) frequency

Frequency is the amount of oscillations per second, which means it's the amount of troughs and crests found within a second.

Answer 2

Answer: The correct option is C.

Step-by-step explanation:

Amplitude is the maximum displacement of the particle from its equilibrium position.

Wavelength is the distance between the two consecutive troughs or crests.

Frequency is the number of complete oscillations per unit time. The SI unit of frequency is Hertz.

Frequency measures the number cycles which occur in a given time. The number of troughs per second in a wave diagram can be found by the frequency.

Therefore, the correct answer is "Frequency".
