A term for the top -most point of a wave is the __ (1 point) trough. frequency. amplitude. crest.

## Step 1
The question is asking for the term that describes the top-most point of a wave. The options provided are "trough", "frequency", "amplitude", and "crest".
## Step 2
The term "trough" refers to the lowest point of a wave, which is the opposite of the top-most point.
## Step 3
The term "frequency" refers to the number of waves that pass a point in a given time period, which is not related to the top-most point of a wave.
## Step 4
The term "amplitude" refers to the maximum displacement of a wave from its rest position, which is not the same as the top-most point of a wave.
## Step 5
The term "crest" refers to the top-most point of a wave, which is the correct answer.
