O J. nm 1 O J. m-1 OJ-I.nm Evaluate Correct! 4) Other Linearization Choices 0/2 points When using x =1/A, the meaning of the slope is hc. There is more than one way to make this data linear, though. For example, instead of choosing x 1/A, you could also choose x = c/A. What would the slope mean in this case? Note that in reality, your choices of variables may be limited by the goals of your experiment, the data available, and the model to which you are fitting your data. Evaluate Incorrect: You're looking for an algebraic representation. If this question had asked the meaning of the slope when y = E and a = 1/A, you would have answered hc. 5) Planck's constant 16 point Other than aesthetics, why would it be useful to fit data with a straight line? Real data is noisy. Often with noisy data, the trend will be more accurate than using a single point. c auantired a crucial understanding in the dexelonment of guantum mechanics. The equation is
