Reflecting on a textbook error

Page history last edited by Joe Redish 5 years, 7 months ago

9.2.P26

 

 

The figure at right is taken from the first edition of a popular standard textbook. In the first column is shown a pulse approaching and reflecting from a fixed end. In the second column is shown a pulse approaching and reflecting from a free end (ring sliding on a frictionless rod). At least six (6!) of the figures are incorrect. State which and explain why.

 

(Hint: The second edition of the book fixed most of the problems by making the pulses symmetric.)
