# How does a wave lose energy?

## How does a wave lose energy?

As it travels, a sound wave’s energy is slowly lost as heat. Because a gas, such as the air, presents less friction to a sound wave than a solid, it can travel a longer distance before all it’s energy is lost.

Do waves lose a lot of energy or very little energy as they cross the ocean?

The period of the tsunami waves may range from 5 to 90 minutes. Tsunami waves in the deep ocean can travel at high speeds for long periods of time for distances of thousands of kilometers and lose very little energy in the process. The deeper the water, the greater the speed of tsunami waves will be.

Can waves carry matter?

It is important to remember that all waves transfer energy but they do not transfer matter .

### How is wave energy related to other forms of energy?

Wave Energy. Many forms of energy are carried in heat, light, sound, and water waves. Energy is defined as the ability to do work; all forms of energy can be transformed into work. In science, work is defined as the movement of an object in the direction of the force applied to it. Waves do work when they move objects.

How are gravity waves related to edge waves?

Edge waves have a longshore periodicity and amplitude decaying exponentially offshore, their energy being trapped against the shore by refraction. They absorb energy from the incoming surface waves. The water-level fluctuations at the water line are therefore the compound result of gravity waves, bound waves, edge waves, and tides.

When do deep water waves change into breaking waves?

When deep-water waves move into shallow water, they change into breaking waves. When the energy of the waves touches the ocean floor, the water particles drag along the bottom and flatten their orbit (Fig. 4.18 B). Transitional waves occur when the water depth is less than one-half the wavelength (D < 1/2 L).

## Why does the top of a wave move faster than the bottom?

Because of the friction of the deeper part of the wave with particles on the bottom, the top of the wave begins to move faster than the deeper parts of the wave. When this happens, the front surface of the wave gradually becomes steeper than the back surface.
