JEE Mains · Physics · STD 11 - 14. waves and sound
The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is
- A \(4:1\)
- B \(1:2\)
- C \(1:4\)
- D \(1:1\)
Answer & Solution
Correct Answer
(A) \(4:1\)
Step-by-step Solution
Detailed explanation
\(C=\sqrt{\frac{\gamma R T}{M}}\) \(C \propto \frac{1}{\sqrt{M}}\) \(\frac{C_{H_2}}{C_{O_2}}=\sqrt{\frac{32}{2}}=4: 1\)
