A wire having a linear density of 0.05 g//cm is stretched between two rigid supports with a tension of 450N. It is observed that the wire resonates at a frequency of 420 Hz. The next higher frequency at which the same wire resonates is 490 Hz. Find the length of the wire.

(i) A wire is stretched between two rigid supports. It is observed that the wire resonates at a frequency of 420 Hz. If a wooden bridge is placed at the midpoint of the wire (so that the midpoint becomes a node), it was observed that the smallest frequency at which the wire resonates is 420 Hz. Find the smallest frequency at which the wire will resonate when there is no wooden bridge. (ii) A string of length L is fixed at one end and is under tension due to a weight hanging from the other end, as shown in the figure. The point of the string on the pulley behaves as a fixed point. Coordinate axes are chosen so that the horizontal segment of the string runs from x = – L // 2 to x = L // 2 . The string is vibrating at one of its resonant frequencies with transverse displacement (y) given by y(x,t) = 0.05 cos(12.0x) sin(360t) with x, y in meter and t in second. Write two smallest possible values of L consistent with the given equation?
