Dear professor, thanks for this valuable video. I have a question, according to the formula, surface plasmon frequency is equal to plasma frequency over square root of 3, so surface plasmon frequency is proportional to plasma frequency. Then can I infer that there is a red shift for the surface plasmon frequency of copper compared to gold.
