----- waves dont need a mudium to transfer energy they mobe through enpty space to transfer energy
You are partially correct. Waves can indeed transfer energy through empty space, but it depends on the type of wave. Electromagnetic waves, such as light and radio waves, can travel through a vacuum because they do not require a medium to propagate. These waves can travel through space and transfer energy from one place to another.
However, there are other types of waves, such as mechanical waves, that do require a medium to transfer energy. These waves, like sound waves or water waves, rely on particles in a medium to propagate. In the case of sound waves, for example, they require molecules in a solid, liquid, or gas to vibrate and transfer energy.
So, while electromagnetic waves can indeed transfer energy through empty space, not all types of waves are able to do so.
