The quaggas of the wave, which are the midpoints, start to spasm out of control.
The molecules vibrate perpendicular to the direction of propagation or motion.
Up to a crest, then down through a trough, then back. APEX :P
a medium. but longitudinal waves do not have to travel through a medium. This is why transverse waves cannot vibrate through space.a medium. but longitudinal waves do not have to travel through a medium. This is why transverse waves cannot vibrate through space.
perpendicular to or at right angles to their direction of motion
Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.
B. at right angles to the direction in which the wave travels
It makes the molecules vibrate so the density chages. Your question is a bit unclear.
sound travels through materials through molecules as we talk through our vocal box the molecule present in the air material start to vibrate it is because the material contain air as they vibrate we hear sound
In order for sound to travel, there has to be something with molecules for it t travel through. On Earth, sound travels by vibrating air molecules, there are no molecules in space, nothing to vibrate
Compression waves (as opposed to transverse waves).
Compression waves (as opposed to transverse waves).
during the propagation of traverse wave the molecules of medium vibrate up and down from mean position in the form of crest and trough.Example:wave in spring,wave in waterWater is the typical example given, but the water wave is a compressive wave at a boundary -- sort of a half transverse wave. Light is the physic's transverse wave. It too should be looked at suspiciously.
