Class 7 Science — Light Important Questions with Answers (Short answers)

Class 7 Science is the first full year photosynthesis, acids-bases and electric current share one textbook. The rationalized NCERT dropped a few older chapters; what remains is the set CBSE still samples in periodic tests. This hub writes one unique paragraph and a question cluster per surviving chapter so “nutrition in plants class 7 important questions” and “heat class 7 MCQ” resolve to real practice, not an empty subject shell. Answers stay behind a tap. Hindi and English stems sit together because most school papers are bilingual.

Light — प्रकाश

Light travels in straight lines; that is why shadows have edges. A real image can be caught on a screen; a virtual image cannot. Concave mirrors converge, convex mirrors diverge, a plane mirror keeps size and reverses left-right. Newton’s disc and the spectrum through a prism are the colour story. Class 7 does not ask mirror formula; it asks ray sketches and uses (make-up, vehicle, torch). You are on Light (Short answers), page 1 of 1 — 3 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.
