JEE MainPhysicsWavesMCQ+4 / −1
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–1 . Approximate value of T is
  1. A
    12°C
  2. B
    15°C
  3. C
    4°C
  4. D
