A pipe of length L will support the lowest fundamental frequency in which of these cases?
  1.if it were closed at both ends
  2.if it were open at both ends
  3.if it were open at one end and closed at the other
  4.All of these cases support the same fundamental frequency because the pipe is the same length for each case.

Question 2

You have a guitar string tied at both ends. You pluck it and you get as a fundamental frequency an A note of 440 Hz. If you wanted to adjust the string to get the next A note one octave higher (880 Hz) as a fundamental frequency, what could you do?
  1.double the string tension
  2.halve the string tension
  3.quarter the string tension
  4.quadruple the string tension
