Question

Susie is measuring the different parts of a transverse wave and recording notes in her journal. Which of the following will she be able to measure using the crest or trough of a single wave? A. the energy; It is only found in the crest or trough of a wave. B. the frequency; It is the distance between crests and troughs. C. the wavelength; It is measured by how fast the crest passes. D. the amplitude; It is measured by the center line of a wave to the crest or trough.

Answer 1

Answer: Option D: The amplitude: It is measured by the center line of a wave to the crest or trough.

Step-by-step explanation:

Using the crest or trough of a single wave, wavelength, frequency, amplitude and energy can be measured.

The energy is measured using the amplitude and frequency of the wave. Hence, option A is incorrect.

The frequency is how fast the crest passes i.e. Number of oscillations per second. It is inversely proportional to the wavelength of the wave which is the distance between two crests or troughs. Hence, both the options B and C are incorrect.

The amplitude is the center line of a wave to the crest or trough. Hence, option D is correct. Amplitude can be measured using the crest or trough of a single wave.
