Consider a 0.385 g/m violin string of 0.15 m length that is clamped at both ends. [4] If a 0.385 g/m violin string of length 0.15m is clamped at one end, and the other end is tied to a small strong fibre of negligible linear density, then how much tension is required in the string for its fundamental frequency to be 220 Hz? 1.1) 1.2) [4] Suppose the violin string is again clamped at both ends under tension. You pluck it and notice a 2 loop standing wave. Holding a 1000 Hz tuning fork in the vicinity you hear a 1.0 Hz beat frequency. Under how much tension is the string now?
