Question

On a particular day, the height of the tide at east coast park was 0.8m at dawn. At dusk, the height of the tide increased by 40?

Answer 1

The amplitude of a wave with a crest measuring 2 meters above the still water mark in the harbour is 2 meters, representing the maximum displacement from the rest position.

Step-by-step explanation:

When considering the height of a tide or a wave, it's important to understand the concept of amplitude. The amplitude of a wave is the distance from the still water level (also known as the mean water level) to the crest (the highest point of the wave). If the crest of a wave measures 2 meters above the still water mark in the harbour, then the amplitude of that wave is simply 2 meters. This is because the amplitude is already measured from the midpoint (still water mark) to the crest, representing the maximum displacement of the wave from its rest position.
