The absolute temperature of air in a region linearly increases from 00C to 8190C in a space of width 'd'. Time taken by sound wave to travel through this space is: [Velocity of sound at 00C is v0]
A
5v2d
B
v6d
C
3v2d
D
None of these
Answer
5v2d
Explanation
Solution
l1 + e = 4λ
l2 + e = 43λ
l2 + e = 3(l1 + e)
l2 = 3l1 + 2e
