ICSE Class 10 Sound — Mock Test (2027)
Free online mock test for Sound (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 Sound 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.Which of the following best describes damped vibrations and their displacement-time graph?
Damped vibrations
Free vibrations- A.Vibrations with constant amplitude over time due to no resistive forces.
- B.Vibrations with increasing amplitude over time due to external energy input.
- C.Periodic vibrations with decreasing amplitude due to resistive forces like friction.
- D.Non-periodic vibrations with random amplitude changes over time.
-
2.What do the terms (1) amplitude and (2) frequency of a wave refer to?
- A.(1) Distance between two crests; (2) Time taken for one vibration.
- B.(1) Maximum displacement from mean position; (2) Number of vibrations per second.
- C.(1) Speed of the wave; (2) Wavelength of the wave.

4.Assertion: Waves produced in a cylinder containing a liquid by moving its piston back and forth are longitudinal waves. Reason: In longitudinal waves, the particles of the medium oscillate parallel to the direction of propagation of the wave. (a) Both assertion and reason are true and reason is the correct explanation of assertion. (b) Both assertion and reason are true but reason is not the correct explanation of assertion. (c) Assertion is true but reason is false. (d) Assertion is false but reason is true.
- a.Both assertion and reason are true and reason is the correct explanation of assertion.
- b.Both assertion and reason are true but reason is not the correct explanation of assertion.
- c.Assertion is true but reason is false.
- d.Assertion is false but reason is true.
