NO, WAIT, THAT'S THE WRONG PROBLEM!!>> Yeah course it is,.......how can a left handed nut have anything to do with light being pulled , bent?, toward a gravitational source!!! :-) from: http://www.geocities.com/CapeCanaveral/Hangar/4317/redaw.html ".................energy change, which manifests itself as a change in frequency in this case since the speed of light cannot change, ..............................." and contradicted by: ( not to mention considerable waffling room :) "We are assuming that when light slows down, its apparent frequency is unchanged. However, other assumptions can also be considered." Of course Marc, all this applies to light and speeds/distances incomprehensible to most of us and the question was about sound (pitch) changing from cold to hot or hot to cold. I have an 8" long X 2" dia. iron rod.......question: will the pitch caused by an 'A' fork struck and held onto one end of that rod be attenuated differently when the rod is 120F and when it is 40F, with the resulting pitch being measured at the opposite end of the rod in each case ? I'ma gonna be tries dis in de mornin. Jim Bryant (FL)
