Q16JEE Main 2023 · 6 APR · SHIFT 2Easy

Speed of Waves

The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is:

Show answer and solution

Answer: (d)

Both diatomic (same $\gamma$ ), same $T$ : $v \propto \dfrac{1}{\sqrt{M}}$ .
$\dfrac{v_{H_2}}{v_{O_2}} = \sqrt{\dfrac{32}{2}} = 4$
So the answer is (d) $4:1$ .
