Compare and Contrast Light And Sound. I NEED HELP! HELP! NOW NOW NOW!!
Amy F is right. They are both waves that can be seen or heard and ect...
Both are waves, and both can be perceived by humans. Light travels much faster than sound, and because it's an electromagnetic wave, it can travel through a vacuum. Sound is a physical wave and needs a medium like air or water to travel through.
speed of sound = 344 miles per second. speed of light = 186,282.397 miles per second. Sound is air particles bouncing off each other in a wave motion, caused by vibration and movement.(compression / shock wave) Light is visible electromagnetic energy. Light behaves as both waves and particles. When light hits an object some of the light is obsorbed and some bounces off, the colors people see are the particles and waves of the light that bounced off an object.
