3) A 10 kHz sound wave with amplitude 2.0 mm is propagated through air at 24°C. Write the equations describing the traveling waves.
4) Given: steel wire with mass 22.0 g and length 1.25 m, fixed at both ends. Determine (a) wave speed on the string and the required tension that will produce the desired fundamental frequency of 42.5 Hz.
5) Two adjacent or successive modes of a pipe are found to be at 780 Hz and 900 Hz. Air temperature is 18°C.
a) Calculate the fundamental frequency and length of this pipe.
b) Determine whether the pipe is open at both ends or open at only one end.
