One piece of evidence that waves transfer energy is that they can cause movement or vibrations in objects they encounter. For example, sound waves can make objects vibrate, and ocean waves can move boats. Additionally, waves can also do work, such as generating electricity in wave power plants.

In a perfect vacuum, electromagnetic waves do not transfer energy. This is because there are no particles or medium for the waves to interact with, leading to no energy transfer.
One piece of evidence that waves transfer energy is that when waves interact with objects, they can cause them to move or vibrate. This movement demonstrates that energy is being transferred from the wave to the object. Additionally, wave energy can be harnessed in various forms, such as in the case of ocean waves being used to generate electricity.
Electromagnetic waves, such as light and radio waves, transfer energy through oscillating electric and magnetic fields. In addition, mechanical waves, like sound waves, transfer energy through the vibration of particles in a medium.
Waves transfer energy, not matter. This energy can be in the form of sound, light, or motion. Waves help transmit information through space.
Electromagnetic waves transfer thermal energy through radiation. These waves include infrared radiation, which is commonly associated with heat transfer.
