Linear Polarization Interference: Can It Happen?

Click For Summary
Linear polarization interference occurs when two linearly polarized waves, one aligned with the x-axis and the other with the y-axis, interact. In a vacuum, these waves do not interfere because their electric fields are orthogonal, meaning they do not combine to form a resultant wave. The absence of matter that could alter the polarization is crucial, as any medium could potentially change the alignment and allow for interference. The discussion emphasizes the importance of understanding wave properties and polarization in physics. Ultimately, the consensus is that without external factors, linear polarization does not lead to interference.

Two waves are linearly polarized. The electric field of one wave is aligned with the x-axis and the other is aligned with the y-axis. In the absence of matter that might change the polarization, can these waves interfere with each other?

You need to show some effort - we aren't here to do your work for you. So, what do you think, and why?
