STANDARD Physics Speed of Sound MCQ Question
Type: MCQ-conceptual-Medium-Class 11
At what temperature will the speed of sound in air be 3 times its value at 0°C?
A
1184°C
B
1148°C
C
2184°C
D
2148°C
Correct Answer
Option C
Detailed Explanation
The speed of sound in air is proportional to the square root of the absolute temperature. If the speed is 3 times, then (273 + t)/273 = 9, solving gives t = 2184°C.
