Presentation transcript:

Both ends of the pipe will vibrate. Open-Ended Pipe How can this make noise? -hit with a mallet -blow into one end Both ends of the pipe will vibrate. A vibrating section of a material is an antinode. The length between two antinodes is ___ λ. Thus, L = ½ λ 1/2

Two types of open-ended pipes: Different pipe length = Different frequencies When the holes are covered, air Comes out of the end – long wavelength When a hole is open, air escapes there Instead– short wavelength

Examples of open-ended pipes:

The closed end will not vibrate. This is a node. Close-Ended Pipe How can this make noise? -hit with a mallet -blow across the top The closed end will not vibrate. This is a node. The open end will vibrate. This is an antinode. The length between a node and a antinode is ___ λ. Thus, L = ¼ λ 1/4

Examples of close-end pipes:

The ends of the string are fixed. These are nodes. How can this make noise? -pluck The ends of the string are fixed. These are nodes. The center of the string will vibrate. This is an antinode. The length between two nodes is ___ λ. Thus, L = ½ λ 1/2

Examples of string instruments:
