Explanation:

Jeff knows that the radio produces sound energy because he can hear music coming from the radio.

The music from the radio is a form of sound energy.

• Sound energy is a form of energy dissipated from a body and can be discerned by humans.
• Sound is a mechanical wave that requires a material medium for its propagation.
• It travels by series of rarefaction and compression along its path of motion.
• Since sound energy is an energy in motion, it is a kinetic energy.
• It travels parallel to its source and therefore, it is a longitudinal wave.
