I would like see the reasons why light is not considered as a LWave
DaleSpam said:I don't know how much more clear I can be. Longitudinal waves cannot be polarized. Light can be polarized. Therefore light cannot be a longitudinal wave.
Sure, take two polarizing filters (e.g. lenses from sunglasses), make light pass through both, and rotate them relative to each other to see light be blocked completely or pass.Trojan666ru said:How do we find that light can be polarized? Any experiment?

I would like to hear the reasons
It can be polarised! What?
Light is not considered as a longitudinal wave because it does not exhibit the characteristics of a longitudinal wave. Longitudinal waves require a medium to travel through, and light can travel through a vacuum. Additionally, longitudinal waves have compressions and rarefactions, while light travels as an electromagnetic wave with oscillating electric and magnetic fields perpendicular to each other.
There are several pieces of evidence that support the idea that light is not a longitudinal wave. One is the fact that light can travel through a vacuum, while longitudinal waves require a medium. Another is the polarization of light, which is only possible with transverse waves. Additionally, the behavior of light in diffraction and interference experiments is more consistent with the behavior of transverse waves.
Understanding that light is not a longitudinal wave is important because it allows us to accurately describe and predict the behavior of light. By recognizing that light is an electromagnetic wave, we can use mathematical models and equations that accurately describe its properties and interactions with matter. This understanding also helps us develop technologies such as fiber optics and lasers.
No, light cannot behave like a longitudinal wave. The nature of light as an electromagnetic wave is fundamental and cannot be altered. While light may exhibit some properties similar to longitudinal waves, such as refraction, these can be explained by the wave-particle duality of light and do not indicate that light is a longitudinal wave.
The understanding of light as an electromagnetic wave has had a significant impact on various areas of science, including physics, chemistry, and engineering. It has allowed for the development of technologies such as lasers, fiber optics, and solar panels. Additionally, this understanding has led to breakthroughs in our understanding of the universe, including the discovery of the electromagnetic spectrum and the role of light in the formation of stars and galaxies.
