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.The amplitude of a sound wave is increased from $1 \, \mathrm{mm}$ to $2 \, \mathrm{mm}$. The loudness of the sound will:
- a.same
- b.decrease
- c.increase two time
- d.increase four times
-
2.Assertion: The velocity of sound increases with increase in humidity. Reason: Velocity of sound does not depend upon the medium. (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.
