Answer:
Mechanical waves need matter to transfer energy while electromagnetic waves do not. ... Waves change direction when they move from one material into another (matter) through the process of refraction. The wave will change direction when the speed of the wave changes.
According to de Broglie's hypothesis, matter is associated with matter waves. Any massive particle moving with a certain velocity can be represented as a superposition of waves whose maxima is the position of the particle.
Relation between waves, energy, and matter:
- The matter is a physical substance that occupies space and possesses rest mass and volume.
- Energy is the quantitative property of a material that is transferred from one object to another in order to perform work or to release heat.
- And Wave is the disturbance of one or more fields in such a way that field values oscillate repeatedly about a stable equilibrium.
- Waves need matter to travel through it. Energy is needed for a matter to change its state.
