Ray Optics, Optical Instruments for Physics 2026

For JEE Main 2026, Ray Optics and Optical Instruments will continue to play a crucial role in the Physics section. Questions are often direct, numerical-based, and less time-consuming if concepts are clear. Topics like reflection and refraction, ray diagrams, image formation, and working of optical instruments are regularly tested. Due to its predictable nature and consistent weightage, this chapter offers high return on preparation time and should not be skipped by serious aspirants.

JEE Main 2026: Key Instructions for Aspirants

• Focus on ray diagrams, mirror and lens formulae, and optical instruments such as microscopes and telescopes. Clear understanding of image formation and magnification helps solve questions quickly and accurately.
• Practice previous year questions (PYQs) from at least the last 10 years, as many JEE Main questions follow similar patterns with slight numerical variations.
• Revise sign conventions and numerical problem-solving techniques regularly, since small mistakes in signs or calculations can lead to incorrect answers.
• Strengthen conceptual clarity in basic principles of reflection, refraction, and lens combinations to avoid errors during lengthy calculations.
