A student creates a Rydberg plot of 1/n2 versus photon energy using his/her data from part 3. The value s/he calculates for the resulting slope is 5 x 1017. What did s/he do incorrectly, and what should the correct value for the slope be? O a. A Rydberg plot is created by plotting 1/n4 versus photon energy. b. The correct value for the slope is 7 x 10^-18 O A Rydberg plot is created by plotting photon energy versus 1/n2. c. The correct value for the slope is 2 x 10^-18 The student must have used individual data points to calculate the slope. d. The correct value for the slope is 4 x 10^17. The student must have plotted the photon energy in k) instead of J. e. The correct value for the slope is 5 x 10^20.
