No. The energy of the wave moves thru the molecules that carry it.
The molecules vibrate perpendicular to the direction of propagation or motion.
I know it ends with a question mark but that is not a question, it's a statment
B. at right angles to the direction in which the wave travels
The quaggas of the wave, which are the midpoints, start to spasm out of control.
The more closely packed molecules are in a medium, the faster sound travels through the medium, so sound travels slowest through a gas under low pressure.
Sound travels through a medium by vibrations of the molecules in the medium .The denser the medium the easier the sound propagates.Iron has higher density than copper and therefore it travels quicker through iron than copper.
Sound travels faster through denser media because their molecules are closer together.
Sound travels faster through denser media because their molecules are closer together.
The material through which a wave travels is called the medium.
Sound waves are vibrations through a medium, such as air or water. The energy travels from the vibrating source and vibrates molecules in the medium, which push others sending a wave through the medium. Without a medium, there's nothing to vibrate and sound cannot travel.
Molecules making up the air are far apart compared to the molecules making up any solid medium. As solids provides very less inter and inter molecular space, light often travels slowly through solid medium. Refractive index of air is 1.
The speed of sound depends on the medium through which it is traveling. Sound travels fastest through solids, then liquids, and slowest through gases. As the molecules in a solid medium are closely packed together, sound waves can travel more quickly through it. Sound waves travel over 17 times faster through steel than through air. The molecules in a liquid medium are also more close together than a gaseous medium, so sound travels 4 times faster in fresh water as compared to air. In a gas, sound can travel only when molecules collide with each other, and as the molecules are quite far apart, the speed is slowest in gases.
