Understanding Longitudinal Standing Waves

What is the primary purpose of the sinewave generator in the experiment?

• To measure the frequency of the spring

• To vibrate the speaker diaphragm at a specific frequency

• To amplify the sound produced by the spring

• To stabilize the spring's movement

At 35 Hz, what phenomenon is observed in the spring?

• The spring breaks

• A standing wave with nodes and anti-nodes is formed

• A single node is formed

• The spring stops vibrating

What is the role of the node card in the experiment?

• To change the frequency of the sinewave generator

• To increase the amplitude of the wave

• To identify the location of nodes and anti-nodes

• To measure the frequency of the wave

What happens to the number of nodes when the frequency is increased to 64.3 Hz?

• The nodes disappear completely

• The number of nodes doubles

• The number of nodes remains the same

• The number of nodes decreases

At 95 Hz, what pattern is observed in the spring?

• The spring breaks

• An alternating pattern of nodes and anti-nodes

• The spring stops vibrating

• A single node is formed
