Physics - Ray Optics

Practise 205 MHTCET previous year questions on Ray Optics, compiled from papers spanning 2007 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty MHTCET tests.

Ray Optics has been asked in 16 of the 17 years of MHTCET papers analysed (2007–2026), with 205 questions in all. 44% of them were easy, 44% moderate and 11% tough. Most of its questions came from 2024, with 40 questions that year. In the last three years (2024–2026) it had 78 questions across 59 papers, about 1.3 per paper.

The chapter's 9 topics are not weighted equally: Refraction of light from plane surface (65 questions, 32%), Lens Formula, Refraction of light from curved surface (46 questions, 22%), and Optical Instruments (34 questions, 17%) have been asked the most. Refraction of light from plane surface has also led over the last five years, with 36 questions. Refraction of light from plane surface has produced the most tough questions (9).
