I asked the above question with the tag specific-reference. The purpose behind doing so is that the tag page suggests
if one has a specific topic to ask, by using this tag he or she shall get it
-as per orders issued by physics community of Stack Exchange.
Also, I request to describe the tags more appropriately possible with more examples.
A resource recommendation question is one that asks for a resource (which can be a book, website, or other resource) to learn a topic from. It should have the resource-recommendation tag.
This is not the same as a specific-reference question, which asks for a specific paper in which a derivation or concept is explained.
Mine was asking to show a specific concept so should have been the latter. But thinking about it now, it also asks for experimental evidences, lecture notes etc. So I am just confused about which of the tags to be used.
