Wave Motion and Graph Analysis

The video tutorial explains the differences between snapshot and history graphs using a wave on a string as an example. It details how to create a history graph from a snapshot graph by analyzing the movement of a wave over time. The tutorial also discusses the symmetry and direction of graphs, showing how they change based on the wave's movement direction. A practical example of a wave moving to the left is provided to illustrate these concepts.

What type of graph is used to represent the entire wave at a specific moment in time?

• Line graph

• Bar graph

• History graph

• Snapshot graph

When creating a history graph, what is the first piece of information you need?

• The speed of the wave

• The point on the graph you are observing

• The color of the graph

• The amplitude of the wave

What is the speed of the wave as mentioned in the tutorial?

• 4 meters per second

• 3 meters per second

• 1 meter per second

• 2 meters per second

At T equals zero seconds, what is the displacement of the string at x equals three?

• Maximum displacement

• Minimum displacement

• Zero displacement

• Unknown displacement

At T equals two seconds, what is the position of the leading edge of the wave?

• At 4 meters

• At 3 meters

• At 2 meters

• At 1 meter

What is the displacement of the string at x equals three at T equals three seconds?

• Zero displacement

• Maximum displacement

• Minimum displacement

• Unknown displacement

How does the history graph change when the wave moves to the right?

• It becomes a mirror image of the snapshot graph

• It remains the same as the snapshot graph

• It disappears

• It doubles in size

What is the relationship between the snapshot and history graphs when the wave moves to the right?

• They are perpendicular

• They are identical

• They are mirror images

• They are unrelated

What happens to the history graph when the wave moves to the left?

• It becomes inverted

• It shifts but retains the same shape

• It remains the same as the snapshot graph

• It becomes a mirror image of the snapshot graph

How does the history graph appear when the wave is moving to the left at x equals negative three?

• It decreases

• It gradually increases

• It remains flat

• It snaps up to maximum amplitude
