Physics - Ray Optics

Practise 115 TS EAMCET previous year questions on Ray Optics, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Ray Optics has been asked in 24 of the 24 years of TS EAMCET papers analysed (2001–2024), with 115 questions in all. 43% of them were easy, 43% moderate and 14% tough. Most of its questions came from 2020, with 17 questions that year. In the last three years (2022–2024) it had 24 questions across 17 papers, about 1.4 per paper.

The chapter's 8 topics are not weighted equally: Lens Formula, Refraction of light from curved surface (48 questions, 42%), Prism and Dispersion of Light (24 questions, 21%), and Optical Instruments (13 questions, 11%) have been asked the most. Lens Formula, Refraction of light from curved surface has also led over the last five years, with 18 questions. Lens Formula, Refraction of light from curved surface has produced the most tough questions (10).
