1.	119. A stationary wave is set up in a resonance aircolumn of a glass tube partially filled with waterby holding a tuning fork near open end, the openend of the tube is :(NCERT 1976)(a) Always a nodetot Always an antinode(c) Some times a node and some times anantinode
Answer» The antinode is not exactly formed at the open end, but at a small distance above the open end. This is called the end correction b.
