Compressional Waves
A sound wave is logitudinal because the motion of the medium (air) travels in the same direction as the wave (back and forth).
Longitudinal waves consist particles in a medium (ex of a medium= air) vibrate back and forth in a parallel direction to the direction of the wave is traveling. Example of a longitudinal wave are sound waves. Boom! Opposite of longitudinal waves would be a transverse wave where instead of particles moving in a parallel direction, transverse waves vibrate in a medium, side by side perpendicular to the direction the wave travels to. Example of a transverse wave is a light wave. Hope this helped =]
The wave you are referring to could be a Mexican wave. A wave is produced when particles of the medium(eg.air) move back and forth. This movement moves other objects back and forth. Therefore there is a succession of vibrations, which is called a wave. A group in the wave will be 'compressed' or will have their arms raised, while the group infront of it would be a 'rarefaction' or have their arms put down. Thus this activiting becomes a wave. (Note: We are not referring to electromagnetic waves)
if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
An object will accelerate in the direction of the net force acting upon it. While she is traveling at a consant speed, the forces due to friction, wind resistance, and so forth are countered by the equal-in-strength but opposing force of the engine. When she applies the brakes, the engine is no longer pushing, so there is a net force in the opposite direction of her motion. This net force accelerates her in the opposite direction of her motion -- we call this deceleration. So, long story short, the direction of the net force is opposite to the direction of her original motion (backwards).
It is a rarefaction.
a compressional wave
Transverse wave, i believe
Longitudinal wave. (as opposed to Transverse waves, where the vibrations are perpendicular to the direction of movement.)
A sound wave is logitudinal because the motion of the medium (air) travels in the same direction as the wave (back and forth).
False
a wave in which matter is moved back and forth in the direction the wave is moving
it was ba
When a compression wave travels through a medium, the particles of the medium move parallel to the direction of the wave. Compression waves are commonly called longitudinal waves.
The displacement of the person pacing back and forth travels 5 west 7m west is usually East.
One homonym for "fourth" is "forth," which means forward or onward in direction.
