Answer 1

Answer:

To find the speed of sound in air at room temperature using a resonance tube by ... These points are called antinodes. ... About Resonance column apparatus.

Answer 2

Answer:

The concept behind the resonant sound apparatus is called antinodes

Explanation:  

A point which undergoes maximum displacement along a stationary wave is called antinode. A standing wave comprises of 'nodes and antinodes'.

Nodes are caused when there is no displacement. Hence while performing the resonance column apparatus experiment in a laboratory at a certain height, we can hear maximum sound. This is due to the 'interference' of two waves making it produce maximum sound.
