What are sound and light waves?
"describe that waves are refracted, reflected, absorbed, transmitted or scattered through various materials
Sound is a type of energy that travels in waves and is produced by vibrating objects. Light is also energy that is made up of waves and travels at the speed of 186,000 miles per second. Both sound and light waves can be reflected, refracted, and absorbed.
Sound and Light Waves
Sound Wave: A wave of pressure that is created by vibrating objects and travels through a medium such as air or water. Light Wave: An electromagnetic wave that is visible to the human eye and is usually characterized by its wavelength and frequency. Reflection: The bouncing back of a wave or sound upon hitting a barrier or surface.
Sound waves are the only type of wave that can travel through solids, liquids, and gases. Light waves move faster than sound waves—about 670 million mph versus 1,000 feet per second. Light and sound waves are both influenced by the same law of physics—the wave equation.
