Re: Question: arrival-time puzzle



It was fascinating to see how the students responded.
*) About a third of them said "wavelength". I gave full credit for
this; if the professor didn't notice, I wasn't going to carp if the
students didn't notice.

That is unfortunate. What is wrong with asking for the correct answer?
