Understanding Longitudinal Waves and Displacement Graphs

What type of graph is used to analyze wave problems in the video?

• Velocity against time

• Displacement against distance

• Frequency against amplitude

• Energy against time

In a longitudinal wave, what is the displacement at points of compression and rarefaction?

• Zero displacement

• Variable displacement

• Minimum displacement

• Maximum displacement

What is the direction of motion considered positive in the video?

• Down

• Right

• Up

• Left

How can you determine if a point on a displacement-distance graph is a compression?

• It has the highest displacement

• Neighboring points are moving away from it

• Neighboring points are moving towards it

• Neighboring points have the same displacement

What is a key difference between transverse and longitudinal waves mentioned in the video?

• Longitudinal waves have rarefactions

• Transverse waves have compressions

• Transverse waves are not common in exams

• Longitudinal waves are not common in exams
