I'm having trouble finding cheap (<$100) and effective (90%+ transmission) optical filters for fluorescence, specifically band-passing around 530nm, as narrowly as possible .
Anyone have any suggestions?
Gamma (Cp/Cv) of a gas
Homework Statement
An experimenter adds 980 J of heat to 1.75 mols of an ideal gas to heat it from 10.0 C to 25.0 C at constant pressure. The gas does 234 J of work during the expansion. Calculate gamma (Cp/Cv) for the gas.
Homework Equations
Cv=Cp-nR
Gamma...
^I just tried that, 277= (1/(2x)) *(812/(.00845/.35))^.5, and got x=33cm, so the answer would be 2, but that's not it either
EDIT: Ok nevermind the answer is 1.9 lol. Thanks!
Homework Statement
You are designing a two-string instrument with metal string 35.0 long, as shown in the figure . Both strings are under the same tension. String has a mass of 8.45 and produces the note middle C (frequency 262 ) in its fundamental mode.
