A wave is a disturbance that transfers energy from one place to another. A wave transfers energy in the direction that it travels. Waves can travel as a single pulse or as a repeating series. Explain how a wave transfers energy from one place to another

We know that the energy we are talking about here can involve both potential energy and kinetic energy, but in wave mechanical concept, we normally consider only kinetic energy, since a wave profile moves with velocity v towards a certain linear motion (since electromagnetic waves travel in a straight line) with a particle in it of mass m, then the total energy possessed by the particle in wave motion is equal to the energy of the wave, traveling from one point to another

B, if it was a lower watt she could put it in for her normal time and not burn it

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
