The discussion focuses on determining the linear density of a string experimentally in Melde's Lab, which examines the relationship between frequency and tension in standing waves. Participants emphasize the necessity of weighing the string and measuring its total length to calculate linear density accurately. Without these measurements, experimental determination is impossible. The conversation highlights a gap in the lab procedure that needs addressing for accurate results.

You have to weigh the string and measure its length.NIZBIT said:This lab is basically the relationship between frequency and tension for a standing wave. One question I have though. In the lab I'm doing it states, "Calculate the linear density and determine it experimentally..." Calculating it is no problem, but how can I determine it experimentally? We never weighed or measured the total length of the string so I don't see how this can be done
