A light source emits visible light of two wavelengths:
1 = 430 nm and l = 510 nm. The source is used in a
double-slit interference experiment in which L = 1.50 m
and d= 0.025 0 mm. Find the separation distance between
the third-order bright fringes.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
