A loud sound is heard when a 570 Hz tuning fork vibrates over the top of a pipe that is open at one end. The pipe is 168 cm long. If the pipe is resonating at the 3rd resonant length, what is the wavelength of the sound waves?

Before the 1940s, the average temperature was cooler than the baseline temperature (1950-1980), but beginning in the 1970s and 1980s, the average temperature was warmer than the baseline temperature. This shows that the average temperature has increased between 1880 and 2010 (~1 degree celsius increase).
