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. nothing can be decided

Answer 1

The correct option is C

during winter

The explanation for the correct option:

1. The speed depends upon the factors such as pressure, temperature, and elasticity of the medium.
2. During winter the temperature is very low and thus sound takes maximum time to travel from one place to another because the speed of the sound wave is directly proportional to the temperature.

The explanation for the incorrect option:

1. During the night the temperature is not that low hence sound can take some time to travel from one place to another.
2. During summer the temperature is high in comparison to winter, thus the speed of sound is minimum.

Hence, option (c) is correct.
