NEET Physics Transverse & Longitudinal Waves MCQ Question
What is the relationship between the speed of sound in a medium and its density according to the NCERT content?
The speed of sound is directly proportional to density.
The speed of sound is inversely proportional to density.
The speed of sound does not depend on density.
The speed of sound varies with the temperature only.
Correct Answer
Detailed Explanation
The speed of sound in a medium is inversely related to its density, as indicated by the formula v = √(B/ρ), where B is the bulk modulus and ρ is the density. This relationship shows that as density increases, the speed of sound decreases.
