These are the waves which require no material medium for their production and propagation, i.e., they can pass through vacuum and any other material medium. For example, waves on water surface, waves on strings, sound waves etc. These waves are governed by Newton’s laws of motion. Mechanical waves can be produced or propagated only in a material medium. Waves are mainly of three types: (a) mechanical or elastic waves, (b) electromagnetic waves and (c) matter waves. (iii) During wave motion only transfer of energy takes place but not that of a portion of the medium. (ii) Each successive particle of the medium executes a motion quite similar to its predecessors along/perpendicular to the line of travel of the wave. (i) The particles of the medium traversed by a wave execute relatively small vibrations about their mean positions but the particles are not permanently displaced in the direction of propagation of the wave. ![]() The characteristics of waves are as follows: Wave is a form of disturbance which travels through a material medium due to the repeated f periodic motion of the particles of the medium about their mean positions without any actual Lakhmir Singh Science Class 8 Solutions.PS Verma and VK Agarwal Biology Class 9 Solutions.NCERT Solutions for Class 9 Foundation of IT. ![]()
