If the temperature of the medium is made 16 times its normal value, then the speed of the sound waves will increase by a factor of
Answer: 4
Explanation
The speed of sound in a gas is proportional to the square root of temperature (in Kelvin):
v ∝ √T
If the temperature becomes 16 times, then:
New speed = √16 × original speed = 4 × original speed
