Chapter 11, Problem 10P

Assume that the speed of sound in air is 340 m/s for all of these problems unless stated otherwise.

Antarctic ice Radio waves travel at a speed of $\text{1}\text{.7 }\times {\text{ 10}}^{\text{8}}\text{m/s}$ through ice. A radio wave pulse sent into the Antarctic ice reflects off the rock at the bottom and returns to the surface in $\text{32}\text{.9 }\times {\text{ 10}}^{\text{6}}\text{s}$. How deep is the ice? What assumptions did you make to solve the problem?
