What Makes Light Waves Different from Mechanical Waves?

Click For Summary

Homework Help Overview

The discussion revolves around the differences between light waves and mechanical waves, specifically focusing on the classification of light as a transverse wave and the implications of this classification. Participants are exploring the nature of waves in physics, particularly the distinction between mechanical and non-mechanical waves.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to understand why light waves, classified as transverse, are not considered mechanical waves. There is a discussion about the definitions of mechanical waves and the characteristics of light waves, with some questioning the assumption that all transverse waves must be mechanical.

Discussion Status

The discussion is ongoing, with participants providing explanations and questioning each other's assumptions. Some guidance has been offered regarding the nature of mechanical waves and the role of material oscillation, but no consensus has been reached on the classification of light waves.

Contextual Notes

There appears to be confusion regarding the definitions of transverse and mechanical waves, as well as the criteria that classify a wave as mechanical. Participants are grappling with these definitions and their implications for understanding light waves.

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 :wink:

it's the field (non-mechanical) that oscillates up and down​
 
so why light waves are transverse as we know that transverse waves are mechanical waves so why we deal light as mechanical wave?

that's not true :frown:

where did you get that from?​
