Current Question (ID: 15975)

Question:

$\text{When height increases, the velocity of sound decreases:}$

Options:

1. $\text{due to the decrease in pressure.}$
2. $\text{due to a decrease in temperature.}$
3. $\text{as a result of a decrease in both temperature and pressure.}$
4. $\text{statement is wrong.}$

Solution:

$\text{Hint: } v = \sqrt{\frac{\gamma RT}{M}}$ $\text{Explanation: When height increases, there's a decrease in temperature.}$ $\text{Since the speed of sound is influenced by temperature, a decrease in temperature}$ $\text{at higher altitudes leads to a decrease in the velocity of sound.}$ $\text{Hence, option (2) is the correct answer.}$
