Ray Optics — NEET/JEE Questions, Notes & Weightage
Class 12 Optics NEET weightage: Very High 0 questions
Covers reflection and refraction at spherical surfaces, lens/mirror formulas, total internal reflection, prism, and optical instruments (microscope, telescope). One of the highest-yield Class 12 Physics chapters — lens/mirror-formula numericals are tested in nearly every paper.

Why is this chapter so consistently high-weightage?
The lens and mirror formulas apply to an enormous range of setups (combinations of lenses, mirrors, refraction through slabs/prisms), giving examiners many distinct, equally valid numerical variations from the same core formulas.
What is the most common numerical type?
Finding image distance, magnification, or focal length using the lens/mirror formula — often for a combination of two optical elements — is the chapter's signature question format.
