ac power - alternating current. That's what comes out of a wall socket.
The energy of a wave moves forward, causing the disturbance in the medium to propagate. This can be seen as the wave pattern moving through space.
That's because the water doesn't move, either. The water moves back and forth slightly, as a result of the wave; the wave energy moves on, WITHOUT taking the water with it. The wave is not a current.
A wave moves in a repeating pattern of crests (peaks) and troughs (valleys). This pattern represents the alternating areas of maximum and minimum disturbance in the medium through which the wave is traveling.
The wave in a rope is called a "sinusoidal wave." It is a pattern of oscillation or disturbance in which the rope moves up and down in a regular, repeated manner.
Such a wave is called a longitudinal wave.
As a wave moves through a medium, the particles within the medium oscillate or vibrate in the direction of the wave propagation. Energy is transferred from one particle to the next, causing a wave pattern to propagate through the medium without the actual particles themselves moving along with the wave.
The stuff that moves on is the "Energy". The next question may come- what the energy is. It is actually a stuff that enable the journey of any object. It is invisible. When any energy moves, it may be of any pattern. The undulating pattern of energy propagation is called wave.
The energy of a wave moves forward with the wave. A wave is moving energy, and the wave carries it in the direction of propagation.
Compression wave
A wave where the medium moves perpendicular to the direction of the wave is called a transverse wave. Its highest point is called the crest.
A mechanical wave moves its medium by transferring energy through the vibration or oscillation of particles in the medium. As one particle moves, it collides with neighboring particles, transferring energy and causing them to also move in a wave-like pattern. This transfer of energy continues through the medium, allowing the wave to propagate.
An oscilloscope is a device that views electrical current or other oscillations on a cathode ray tube screen. A compression wave, meanwhile, is a type of wave that forms rarefaction when it moves down a channel.
