How does polarizing light demonstrate the transverse nature of light waves?

AI Thread Summary
Polarizing light demonstrates its transverse nature by showing that light waves consist of oscillating electric and magnetic fields that are perpendicular to each other. While light is typically unpolarized, it can be polarized through various methods, which restricts the vibrations to a single plane. The discussion highlights the confusion around what it means for light to be polarized and emphasizes the importance of understanding electric and magnetic fields. It clarifies that the vibrations of electric charges create light waves, but the waves themselves can propagate through a vacuum without the need for material charges. Further reading on the topic is encouraged for a deeper understanding.

Homework Statement


Explain how polarizing light shows light travels as a transverse wave.

The Attempt at a Solution


Light is generally an un-polarized electromagnetic wave but there are different ways that light waves are able to be polarized. I am unclear how the process of polarizing light shows that light travels as a transverse wave.

No. Vibrations of electric charge give rise to light waves, but the waves themselves can travel through empty space where there are no charges to vibrate. The electric and magnetic fields vibrate, and those are not material things.
