Question

Which of the following are true statements about waves?

A. All waves carry matter but not energy.
B. All waves have both an amplitude and frequency.
C. All waves have a repeating pattern.

Answer 1

C because of the power of the water

Answer 2

B,C

Explanation:

B. All waves have both an amplitude and frequency.

C. All waves have a repeating pattern.

A statement A is incorrect, Waves are a disturbance that transfer energy through space without transferring matter.

B is true, All types of waves have an amplitude, which is the measure of the maximum displacement of a point on the wave from its rest position and a frequency, which is the number of complete oscillations of a point on the wave per unit of time.

C is also true, All types of waves have a repeating pattern, which is known as a waveform. The shape of the waveform determines the type of wave. For example, sine waves have a smooth, curved shape, while square waves have sharp, angular edges.
