In that universe, which of the following objects would require quantum mechanics to describe, that is, would show both particle and wave properties? Which objects would act like everyday objects, and be adequately described by classical mechanics? object quantum or classical?

3. Based on the wavelengths you noted during the lab exercise, report the color and calculated frequencies and energies of any three lines (transitions) of your choice from the helium and argon spectra. 550nm Im =5

3, Determine the Rydberg constant from the data. Since for n1 = 2: tad**) Equation 1 릇=-R-G)- Equation 2 4 which is of the form y - mx+ b That is, Equation 2 is of the form of a straight line, hence the Rydberg constant is the negative of the slope. Plot y 1/0 vs. x 1/ni on the graph paper provided, then determine the slope m =-R," Be sure to label the axes of the graph. As a check, compare this value of RH with the y-intercept, which should equal R,(4. To make it easy, set up a table (next page) for the data. Use meters for wavelength; the units of R, will be meter". Show your calculations in the space below:
