A single disturbance that moves from point to point through a medium is called a __ a. wavelength b. periodic wave c. pulse d. period

## Step 1<br />The problem is asking identify the term that describes a single disturbance that moves from point to point through a medium. Let's analyze each option:<br /><br />## Step 2<br />A. Wavelength: This term refers to the distance between identical points (like two consecutive crests or troughs) in the adjacent cycles of a waveform signal. It does not describe a single disturbance.<br /><br />## Step 3<br />B. Periodic Wave: This term refers to a wave that repeats itself at regular intervals. It does not describe a single disturbance.<br /><br />## Step 4<br />C. Pulse: This term refers to a single disturbance that moves from point to point through a medium. This matches the description given in the problem.<br /><br />## Step 5<br />D. Period: This term refers to the time taken for one complete cycle of vibration to pass a given point. It does not describe a single disturbance.
