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
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
The assertion (A) is true:
Sound waves travel faster in solids compared to gases because solids are more rigid and have higher elasticity, which allows the waves to propagate faster.
The reason (R) is false:
Bulk modulus is a measure of a material's resistance to uniform compression. Solids have higher values of bulk modulus than gases, not the other way around. So, gases do not have a higher value of bulk modulus than solids.
