Question

Distinguish between mechanical and non mechanical waves with an example.​

Answer 1

Answer

⚫Mechanical waves

◾These waves can be produced with the help of mechanical or material medium.

◾These waves are also called as elastic waves.

◾These require material medium for propagation and reception

◾Eg: sound waves

⚫Non mechanical waves

◾ These waves are produced by a accelerating charged particles.

◾These waves are non elastic waves.

◾This require electronic oscillator circuit or medium under oscillation and propagates in vacuum.

◾Eg : Electromagnetic waves

Answer 2

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Non-mechanical waves are waves that do not require a medium for the transfer of their energy to occur. Electromagnetic waves are the only type of non-mechanical waves. They can travel through the vacuum of space.
