SUMMARY
Placing a blue filter in front of a light source results in blue light due to the material's allowed electronic transitions and vibrational modes, not polarization. The filter selectively absorbs other wavelengths while transmitting blue wavelengths, which is a fundamental property of the filter material. This phenomenon is rooted in the physics of light and materials, specifically how they interact with different wavelengths.
