Detailed explanation-1: -Do all waves carry energy? Light, heat, radio, and similar types of energy are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM. Some energy waves need a medium, such as water or air, through which to travel.
Detailed explanation-2: -A mechanical wave is a wave that is an oscillation of matter and is responsible for the transfer of energy through a medium.
Detailed explanation-3: -Yes, EM waves carry energy E and momentum P. As electromagnetic waves contain both electric and magnetic fields, there is a non-zero energy density associated with it.
Detailed explanation-4: -A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position. Energy is transported through the medium, yet the water molecules are not transported.
