The correct answer is 'C'. A pulse is a single disturbance that moves from point to point through a medium.
Объяснение
## Step 1The 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:## Step 2A. 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.## Step 3B. Periodic Wave: This term refers to a wave that repeats itself at regular intervals. It does not describe a single disturbance.## Step 4C. 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.## Step 5D. 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.
