Which waves go up and down?
Types and features of waves Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What is a wave that oscillates up and down?
If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave. For transverse waves in matter, the displacement of the medium is perpendicular to the direction of propagation of the wave.
Why wave is up and down?
Transverse Waves The particles do not move along with the wave; they simply oscillate up and down about their individual equilibrium positions as the wave passes by. Pick a single particle and watch its motion.
Why waves go up and down?
Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.
What are waves and tides?
What are rarefactions and compressions?
Longitudinal waves show areas of compression and rarefaction : compressions are regions of high pressure due to particles being close together. rarefactions are regions of low pressure due to particles being spread further apart.
What are compressions and rarefactions explain?
Compression- a region in a longitudinal (sound) wave where the particles are closest together. • Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart.
What happens to a wave when it hits a wall?
If the collision is inelastic, then the wall (or ball) absorbs some of the incident energy and momentum and the ball does not bounce back with the same speed. Waves also carry energy and momentum, and whenever a wave encounters an obstacle, they are reflected by the obstacle.
What makes a wave appear to be standing still?
The resultant wave appears to be standing still, with no apparent movement in the x -direction, although it is composed of one wave function moving in the positive, whereas the second wave is moving in the negative x -direction. (Figure) shows various snapshots of the resulting wave.
Which is an example of how a wave moves?
Notice how the wave moves but the particles just bounce back and forth (longitudinal) or up and down (transverse), but generally do not go anywhere. Example: a wave moves left to right, and the disturbance moves left and right also.
How is a wave a disturbance in space?
A wave is a disturbance that moves through space or matter. The “disturbance” or “variation” can be a change in pressure, electrical intensity or many other things, but there is always a transfer of energy. And waves vary about some central value due to a “restoring” force, such as a spring, magnetic force, surrounding pressure, etc.
