What happens to the particles in a transverse wave?
Transverse Waves In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. 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.
When a transverse wave moves through a medium What is the action of the particles of the medium?
1 Answer. Mark C. They move in a perpendicular direction (at right angles) to the direction of the wave motion.
How would you describe the motion of a transverse wave?
Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
What are transverse and longitudinal waves give an example of each?
In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. Examples of transverse waves include vibrations on a string and ripples on the surface of water. An example of longitudinal waves is compressions moving along a slinky.
What are 3 examples of longitudinal waves?
Some examples of longitudinal waves are sound waves, seismic P-waves, and ultrasound waves.
What are the similarities and differences between transverse and longitudinal waves?
2 Answers. For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
What are the similarities and differences between electromagnetic and mechanical waves?
Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. The mechanical waves need a medium like water, air, or anything for it to travel.
How can you tell the difference between a longitudinal wave and a transverse wave?
In the longitudinal wave, the medium moves left to right, while in thee transverse wave, the medium moves vertically up and down. Longitudinal waves have a compression and rarefaction, while the transverse wave has a crest and a trough. Longitudinal waves have a pressure variation, transverse waves don’t.
What is the difference between transverse and compressional waves?
When a transverse wave moves through matter, it moves particles back and forth at right angles to the direction of wave movement. When a compressional wave moves through matter, it makes the particles shift back and forth in the same direction as the wave movement.
What do transverse and longitudinal waves have in common?
What do transverse and longitudinal waves have in common? they both need something like a medium to travel through (matter) however a light wave can travel through a vacuum. An earthquake wave is a P wave that is longitudinal.
Why light is a transverse wave?
Light is a wave in which an electric field propagates in vacuum or inside a medium. All electromagnetic waves, including light, are transverse waves because they vibrates energy in a direction perpendicular to the direction in which the wave is travelling.
Do longitudinal waves need a medium?
Yes, longitudinal waves need a medium to continue moving forward.
What is a longitudinal wave that needs a medium in order to propagate?
Longitudinal waves include sound waves (vibrations in pressure, a particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave.
Do compression waves need a medium?
Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
What do waves carry from place to place?
Waves carry energy from one place to another. Because waves carry energy, some waves are used for communication, eg radio and television waves and mobile telephone signals.
What is a medium in waves?
A medium is a substance or material that can carry a wave. The wave medium is not the wave and it does not make the wave; it merely carries or transports the wave from its source to other locations.
Can sound waves travel in vacuum explain?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Can sound waves travel through air?
Sound can travel in air at approximately 332 metres per second. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.
How is echo heard?
An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Echoes can be heard in small spaces with hard walls, like wells, or where there are lots of hard surfaces all around.
Why echo is heard in an empty gym?
Sound will echo in an empty room because if there is nothing to stop the sound reflecting between hard surfaces, such as the walls, windows, ceiling, and floor . Since each surface is not a perfect reflector, some of the sound energy will be absorbed by the surface.
What is the formula for echo?
For example, if the speed of sound in water is 1500 meters per second and the fisherman’s sonar device detects an echo in 0.02 seconds, the distance of the object under water will be d = v*t = 1500 meters per second * 0.02 seconds = 30 meters (back and forth).
What is the minimum distance needed for an echo?
Thus, to hear the echo clearly in the air, the reflecting surface should be at a minimum distance of 16.5m from the source of sound.
