How do you measure a wave?


How do you measure a wave?

To measure a wave, you hove to take the distance between its highest point, which is called its crest and its lowest point or trough. Ocean waves are very difficult to measure, since you can’t just climb on a wave and measure it! You need a satellite or a high flying airplane and complicated instruments to measure waves over a large area.
