ICSE Class 10 Light — Mock Test (2027)
Free online mock test for Light (ICSE Class 10 Physics) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Light chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.What happens when a beam of white light passes through a hollow prism?
- A.It produces a full spectrum of colors.
- B.It disperses into a partial spectrum of colors.
- C.No spectrum is produced because dispersion does not occur.
- D.It reflects the light without any change in color.
-
2.You are provided with a printed piece of paper. How can you differentiate between a convex lens and a concave lens by observing the letters on the paper?
- A.Letters appear inverted and magnified for both lenses.
- B.Letters appear erect and magnified for convex, erect and diminished for concave.
- C.Letters appear blurred for both lenses.
- D.Letters appear erect and diminished for convex, magnified for concave.
-
3.An endoscope uses optic fiber to transmit high resolution images of internal organs without loss of information. The principle of light that is used by the optic fiber is based on:
- a.refraction
- b.reflection
- c.scattering
- d.total internal reflection
-
4.21. A ray of light travels from a medium of refractive index n₁ to a medium of refractive index n₂. If angle of incidence is i and angle of refraction is r, then sin i / sin r is equal to
- A.n₂ / n₁
- B.n₁ / n₂
- C.n₁
- D.n₂
-
5.The wavelength of red light is $800 \mathrm{~nm}$. Find its frequency. Speed of light $= 3 \times 10^{8} \mathrm{~m} \mathrm{~s}^{-1}$.
