JEE Main 2025 — Waves and Sound Question with Solution
JEE Main 2025 (28 Jan Shift 1)
Question
Given below are two statements: one is labelled as Assertion A and the other is labelled as
Reason
Assertion A: A sound wave has higher speed in solids than gases.
Reason R: Gases have higher value of Bulk modulus than solids.
In the light of the above statements, choose the correct answer from the options given below

Correct answer
B is true but is false
Step-by-step explanation
Speed of sound in a medium depends on inertial and elastic properties as for gases and for solids. Since the elastic property of solid happens to be many folds greater than that of gases, the speed of sound in solids i5 higher than in gases.
Also, bulk modulus of gases varies between 0 and hence reason is false.
