  • At the simplest level, waves are disturbances that propagate energy through a medium. Propagation of the energy depend on interactions between the particles that make up the medium. Particles move as the waves pass through but there is no net motion of particles. This means, once a wave has passed the particles return to their original position.

  • Electromagnetic Waves have different wavelengths. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.Elasticity is measured as ratio of stress to strain. For a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young's modulus, it can be concluded that steel has greater elasticity than rubber.
