Объяснение
## Step 1The 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:## Step 2A. 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.## Step 3B. 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.## Step 4C. 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.## Step 5D. 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.
