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

## Step 1<br />The problem is asking us to 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. Period: The period of a wave is the time it takes for one complete cycle of the wave to pass a given point. It is not a disturbance, but a measure of time.<br /><br />## Step 3<br />B. Wavelength: The wavelength of a wave is the distance between two consecutive points in a wave that are in phase. It is not a disturbance, but a measure of distance.<br /><br />## Step 4<br />C. Periodic Wave: A periodic wave is a wave that repeats itself at regular intervals. It is not a single disturbance, but a series of disturbances.<br /><br />## Step 5<br />D. Pulse: A pulse is a single disturbance that moves from point to point through a medium. It is not a repeating pattern, but a single event.
