A simple wave has *

1 point
A repeating pattern
specific wavelength
specific frequency & amplitude
All of these

The correct answer is: All of these.

To understand why, let's break it down:

1. A simple wave has a repeating pattern: A wave is defined by its repetitive nature. It consists of a series of oscillations or disturbances that propagate through a medium or space. Each oscillation repeats itself identically over time, creating a pattern.

2. A simple wave has a specific wavelength: Wavelength refers to the distance between two corresponding points on a wave, such as the distance between two adjacent crests or troughs. In a simple wave, the wavelength remains constant throughout, giving it a specific value.

3. A simple wave has a specific frequency: Frequency is a measure of how many complete cycles or oscillations a wave undergoes per unit of time. It is typically measured in hertz (Hz). In a simple wave, the frequency is constant and does not change.

4. A simple wave has a specific amplitude: Amplitude refers to the maximum displacement or distance from the equilibrium position that a wave reaches during its oscillation. It represents the strength or intensity of the wave. In a simple wave, the amplitude remains constant.

Therefore, a simple wave exhibits all of these characteristics: a repeating pattern, a specific wavelength, a specific frequency, and a specific amplitude.
