Nodes and Antinodes

what are the differences between standing waves in a vibrating string and standing waves of air in a pipe

• The air particles move faster than particles in the string and move parallel to the pipe whereas the particles in the string move perpendicular to the length of the string. Nodes form at the open ends of the pipe but antinodes form at the ends of the string

• The air particles move slower than particles in the string and move parallel to the pipe whereas the particles in the string move perpendicular to the length of the string. Nodes form at the open ends of the pipe but antinodes form at the ends of the string

• The air particles move faster than particles in the string and move parallel to the pipe whereas the particles in the string move perpendicular to the length of the string. Antinodes form at the open ends of the pipe but nodes form at the ends of the string

• The air particles move slower than particles in the string and move parallel to the pipe whereas the particles in the string move perpendicular to the length of the string. Antinodes form at the open ends of the pipe but nodes form at the ends of the string

the equation for all the possible wavelengths that can form in a standing wave in a length of string between two fixed ends is

• = 2L/n

• = 2n/L

• =n/2L

• = L/2n
