Class 10 Science — Light — Reflection and Refraction Important Questions with Answers (Short answers)
Class 10 Science is one board paper with chemistry, biology and physics stitched. Chemical equations, life processes, heredity, spherical mirrors, electricity and our environment are the high-traffic searches. This page replaces the old empty subject shell and the three-chapter demo with a full 150+ file bank in the Class 9 style: hidden answers, twenty questions a page, rationalized 2023–26 chapter names only. Use it as a daily test, not as a date rumour about the board.

Mirror formula, magnification, sign convention, lens formula, and power P=1/f (f in metre, P in dioptre). Ray diagrams for the six mirror cases and the lens cases the book draws. Snell and refractive index n=c/v. Numericals use the school sign convention consistently — mix of conventions is the usual error. You are on Light — Reflection and Refraction (Short answers), page 1 of 1 — 2 questions in this filter. Short answers are two-to-four line NCERT points — definition, reason, or a small numerical. Write in the language your school paper uses (Hindi or English) then match the hidden paragraph. These are the 2- and 3-mark stems teachers recycle. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
