Wave Optics Important Questions for NEET Overview 

Wave Optics deals with the wave nature of light. It explains phenomena like interference, diffraction, and polarization. These concepts help in understanding how light waves interact with different surfaces and mediums. NEET often includes numerical and conceptual questions from this chapter, so practicing these is essential.

What are Wave Optics?

Wave optics is the branch of physics that explains the wave nature of light. It describes phenomena such as interference, diffraction, and polarization, which cannot be explained using ray optics. Wave optics helps in understanding how light behaves when it encounters obstacles, slits, or different mediums.
