Hello, I need help or guidance. 1. What are the laws of vibrating string? Does it have something to do with f = (1 / 2L) (T / u)^1/2 where f is frequency, T is tension and u is mass per unit length of the string? 2. What method can I use to determine if the string has the same frequency as the tuning fork? (Well I know that one method is by the sense of hearing) 3. To determine the linear mass density, will I divide my mass of the string to the length of the string? Oh, what "exactly" does linear mass density mean? 4. If the string is vibrating with its fundamental frequency , how is wavelength of the sound produced related to the length of string? Is it directly proportional bec. wavelngth = 2 X Length..? 5. If I would like to find the fundamental frequency of a vibrating string, will I use the formula written on question # 1?
