Which of the following statements is true of sound waves? * Sound waves are found on the electromagnetic spectrum Sound waves do not require a medium to travel through Sound waves can travel through outer space Sound waves are a kind of matter wave, which requires material in order to travel

Sound waves are a kind of matter wave, which requires material in order to travel

Explanation: sound waves travel through air, water or other matter  hence they cant travel in space. Sound waves are longitudinal hence they cant be classified among the electromagnetic waves.

Sound waves are a kind of matter wave, which requires material in order to travel

Explanation: hope this helps ;)

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
