Waves have energy
1. High energy when the waves push forward
2. Low energy when the waves lapping gently along the coast.
Can you differentiate which one is high energy and low energy?
Factor affecting the wave energy
There are several factors that influence wave energy. One of the factor is WIND
The higher the speed of the wind, the higher the wave energy will be.
Another factor is FETCH
Fetch is the distance of open water which the wind blows. Long fetch will cause the waves have high energy.
