A wave that oscillates up and down is called a transverse wave. In a transverse wave, the particles of the medium move perpendicular to the direction of the wave. An example of a transverse wave is a wave on a string.
Tsunamis are usually caused by under-sea earthquakes. The shift in the ocean floor moves vast amounts of water, causing a wave. As the wave nears land, the gradual slope of the coastline causes the front of the wave to slow down, while the back of the wave continues at the the same speed. This causes the wave to 'rear up' to great height.
Tsunamis happen in coastal areas. The tsunami is a huge wave generated by an under-sea earthquake. The quake pushes a piece of the earth upwards, which triggers a deep wave to form. As the wave nears the coast, the front of the wave slows down as the water reaches land. However - the back of that makes the wave 'rear up' to perhaps fifty feet or more in height.
describe the wave pulse that travels down the slinky?
If the wave slows down but its frequency remains the same, the wavelength of the wave will also decrease. This is because the speed of a wave is directly proportional to its wavelength when frequency is constant. Therefore, when the wave slows down, its wavelength decreases proportionally to maintain the same frequency.
When particles move up and down with a wave, this is known as vertical or transverse wave motion. In this type of wave, particles move perpendicular to the direction in which the wave is traveling. This motion creates crests and troughs in the wave pattern.
A wave that causes particles to move up and down is called a transverse wave. In this type of wave, the motion of the particles is perpendicular to the direction of the wave itself. Examples include light waves and water waves.
The type of wave created when shaking a rope up and down is a transverse wave. This means that the wave travels perpendicular to the direction in which the rope is moving.
Any wave has two directions: the up and down direction (primary wave) and the side to side direction (secondary wave).
When a wave slows down, the frequency of the wave remains constant, but the wavelength decreases. This is known as the phenomenon of wave refraction, which happens when a wave encounters a change in the medium through which it is traveling, causing it to slow down.
