Sound Problem...
A swimmer with one ear underwater and one ear above water in air, hears a crash. She hears the crash in the water first where the Veloctiy of the wave in water was 1500m/s. The air temperature is 20°C and she hears the wave again after 2.0 seconds but this time she hears it through the ear that's above the water. Find the distance from the crash...
What I tried was this:
-Vair=332 + 0.59 (20°) = 343.8m/s
-Since she hears the sound in air 2 seconds after it must've traveled at least 343.8*2 = 687.6 m
So is the distance is 687.6 m?
Thx for help...
