You are attempting to create a standing wave with n =7 in a pipe .5 m in length and filled with air. The top of the pipe is open to the air and the bottom of the pipe is barley submerged in water and thus closed.

a) draw the diagram for this standing wave with the proper number of nodes and antinodes for this open closed pipe.

B) calculate the frequency created by this standing wave assuming the air is at room temperature
