The pressure wave, P = 0.01sin[1000 t − 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–1. Approximate value of T is :
(a)
4°C
(b)
12° C
(c)
15° C
(d)
11° C
