Answer: A wave is a disturbance that carries energy from place to place. A wave does NOT carry matter with it! It just moves the matter as it goes through it. Some waves do not need matter (called a “medium”) to be able to move (for example, through space). These are called ...
国际课程课件系列之物理Waves and light.ppt,What Is a Wave? A wave may be thought of as a spreading of disturbance from one place to another. “Ripples.” As ripples spread out, they carry along with them, energy. Wave Motion Common to ALL wave motion. Vib
Waves transfer energy… Properties of Waves What is meant by the axis of a wave? The axis is the line running through the middle of the wave pattern. What is meant by the crest of the wave? The crest is the top part of the wave ...
In the paper we show that the real gravitational waves which have\n$R_{iklm}ot= 0$ always carry energy-momentum and angular momentum. Our proof\nuses canonical superenergy and supermomentum tensors for gravitational field.doi:10.1002/1521-3889(200206)11:6<442::AID-ANDP442>3.0.CO;2-A...

The Nature of Waves What is a wave? A wave is a repeating disturbance or movement that transfers energy through matter or space Waves transfer energy not matter. The water waves below are carrying energy but are not moving. Waves can only exist if they have energy to carry them. ...
