No, electromagnetic waves are not considered mechanical waves. While it is true that electromagnetic waves are transverse waves, they are not classified as mechanical waves.
Mechanical waves require a medium, such as a solid, liquid, or gas, to propagate. These waves transfer energy by causing particles in the medium to oscillate back and forth or vibrate in a particular direction. Examples of mechanical waves include sound waves, water waves, and seismic waves.
On the other hand, electromagnetic waves do not require a medium for their propagation. They consist of varying electric and magnetic fields that are perpendicular to each other and to the direction of wave travel. Electromagnetic waves can travel through a vacuum, such as outer space, where there is no material medium. Examples of electromagnetic waves include radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays.
So, while electromagnetic waves share the property of being transverse waves with some mechanical waves, they differ fundamentally in their nature and do not fall under the category of mechanical waves.
