The pressure wave, P = 0.01 sin (1000t-3x] Nm-2. corresponds to the sound
produced by a vibrating blade on a day when atmospheric temperature is
0°C. On some other day when temperature is T, the speed of sound produced
by the same blade and at the same frequency is found to be 336 ms
Approximate value of T is
1
(A) 15°C
(B) 12°C
(C) 4°C
(D) 11°C

since speed of wave ∝
T
so, =
336
