Question

Sound takes some time to travel from one place to another. It will be maximum

• A. at night
• B. during summer
• C. during winter
• D. it allways remains the same

Answer 1

The correct option is C during winter

Sound travels faster in summer than in winter.The reason is that the speed of the sound is given by the equation:

$v=\sqrt{\frac{\gamma RT}{M}}$

That is,

$v\propto \sqrt{T}$

Here, $v$ denotes the speed of sound and $T$ denotes the

temperature.

So, the velocity of sound increases roughly by $0.61m/s$ per ${}^{0}C$ in

temperature.

Hence, the sound takes more time to travel from one place to another during

winter.
