What Makes Light Waves Different from Mechanical Waves?

[Aadrish]

i have a huge problem. the issue is
" light waves are transverse waves . transverse and longitudinal are the example of mechanical waves . while light waves are not mechanical waves"
can some one explain me

"mechanical" means that there's some material that oscillates

in a sound wave in air, each bit of the air moves forwards and backwards in the direction the wave is moving …

that's longitudinal​

in a wave on water or on a rope, each bit of the water surface or the rope moves up and down (but does not move in the direction the wave is moving)…

that's transverse​

but with light, there's no material to oscillate …

it's the field (non-mechanical) that oscillates up and down​

 

[Aadrish]

so why light waves are transverse as we know that transverse waves are mechanical waves so why we deal light as mechanical wave?

 

[tiny-tim]

… we know that transverse waves are mechanical waves …

that's not true

where did you get that from?​

Light waves are a type of electromagnetic wave, which means they do not require a medium to travel through, unlike mechanical waves. This is why light waves can travel through a vacuum, such as in outer space. While both transverse and longitudinal waves exhibit a characteristic of oscillation, they differ in the direction of their oscillations. In transverse waves, the oscillations are perpendicular to the direction of wave propagation, while in longitudinal waves, the oscillations are parallel to the direction of wave propagation. Light waves are transverse waves because their electric and magnetic fields oscillate perpendicular to the direction of wave propagation. This allows them to interact with matter in different ways, such as being absorbed or reflected, which is why we can see objects and colors. Therefore, while light waves may share some characteristics with mechanical waves, they are fundamentally different in their nature and behavior.
