D. Solids, liquids, and gases

Best Answer

Correct answer is D.

Sound is a form of energy produced and transferred by vibrating matter. Sound travels in waves. There are two different types of wave’s Transverse waves and longitudinal waves. Sound is a case of longitudinal waves. When sound shifts through matter (solid, liquid, and gas), the molecules of the matter move backward and forward in the direction in which the wave is traveling. This movement is called a vibration. Sound travels much faster than liquids and gases through solid because the molecules of a solid are closer together. Sound travels the slowest through gases because the molecules of a gas are furthermost apart. In a vacuum sound cannot travel because there's no matter for it to move through. Sound is like light in some ways it travels out from a definite source (similar as an instrument or a noisy machine), just as light travels out from the Sun or a light bulb. But there are some veritably important differences between light and sound as well. We know light can travel through a vacuum because sun ray has to race through the vacuum of space to reach us on Earth. Sound, still, cannot travel through a vacuum it always has to have individual to travel through (known as a medium), similar as air, water, glass, or metal.
