Assume that temperature varies linearly with height near the Earth.s surface. Considering temperature at the surface of the Earth T_(1)and T_2 at a height h above the surface, calculate the time / needed for a sound wave produced at a height x to reach the Earth.s surface. Velocity of sound at the Earth.s surface is c. |
