Yeah course it is,.......how can a left handed nut have anything to do with 
light being pulled , bent?, toward a gravitational source!!!  :-)

".................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.
