Wave Superposition

Mr. Andersen explains wave superposition, where waves interact to either build up or cancel each other out. He demonstrates how waves move through each other, leading to constructive or destructive interference. The video covers the concept of standing waves, nodes, and antinodes, and suggests experiments to measure wave displacement during interactions.

What happens when two transverse waves meet and superposition occurs?

• They pass through each other and interfere.

• They merge into a single wave permanently.

• They stop moving completely.

• They bounce off each other.

In constructive interference, if two waves are each 1 cm above equilibrium, what is the resulting wave height?

• 1 cm

• 0 cm

• 2 cm

• 3 cm

What is the result of destructive interference when one wave is 1 cm above equilibrium and the other is 1 cm below?

• 0 cm

• 2 cm above equilibrium

• 1 cm below equilibrium

• 1 cm above equilibrium

What is a standing wave?

• A wave that bounces back and forth without interference.

• A wave that appears to be stationary, moving only up and down.

• A wave that moves in one direction only.

• A wave that cancels out completely.

What are nodes in the context of standing waves?

• Points where waves merge permanently.

• Points of maximum displacement.

• Points of no displacement due to total destructive interference.

• Points where waves bounce off each other.
