Question

transversal wave means and non mechanical waves please both of explain

Answer 1

Mechanical vs Electromagnetic Waves

Waves can be divided using several methods. And one such method of differentiating it is by the means of the medium in which they travel. As per the medium, the waves can be differentiated as mechanical and electromagnetic waves. 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. The mechanical waves need a medium like water, air, or anything for it to travel. The ripples made in a pool of water after a stone is thrown in the middle are an example of mechanical waves. Examples of electromagnetic waves include light and radio signals. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Mechanical waves are also called elastic waves as their propagation depends on the elastic properties of the medium through which the waves pass. Electromagnetic waves are caused because of the varying magnetic and electric fields. While mechanical waves are caused by wave amplitude and not by frequency, electromagnetic waves are produced b

Answer 2

Waves are of two types:
Mechanical waves and Electromagnetic waves (non mechanical waves).

• Mechanical waves are waves which needs a medium to travel.
eg : Sound waves and water waves

• Electromagnetic waves do no need a medium to travel
eg: Light rays

Mechanical waves has two classification. They are
1. Transverse waves
2. Longitudinal waves

Transverse waves are waves which travel perpendicular to the direction of the wave motion while longitudinal waves are waves which travel parallel to the motion of the wave motion.

But electromagnetic waves are a class of transversal waves.
