Physics Waves

The speed of a wave can be found by the medium properties through which it travels. For mechanical waves, the speed of the wave depends on the inertia and elasticity of the medium. For example, the speed of a wave is dependent on the mass of the wave per unit length and the tension in the string. 
Also, sound travels in solids at a greater speed than in liquids and gases because, in a solid, the particles are more tightly packed. In the case of electromagnetic waves, the speed of waves is the highest in vacuum and it depends on the magnetic and electric properties of the medium. The type of wave also matters which can be longitudinal and transverse waves. In the same medium, they may travel at different speeds.

According to the principle of superposition, when two or more waves overlap in space, due to each individual wave, at any point the displacement is the vector sum of the displacements. The principle of superposition also explains phenomena like interference where waves combine to amplify or cancel out each other. It can happen in both ways - constructively or destructively. In real life, the superposition can be seen in the noise cancellation technologies, sound beats and the colourful patterns created by overlapping water waves. The principle is the fundamental concept for understanding wave behaviour in acoustics, optics and even quantum physics.
