For a spring that obeys Hooke's law, the tension in the spring is proportional to the stretched length of the spring T = k(L-Lo), where L and L, are the length of the stretched and unstretched spring, respectively, and k is the spring constant. The mass density of the spring is μ = M/L and the wave velocity is v= √√√//μ. Substitution of these expressions into Eq. 6.1 shows that the frequency of the standing waves depends on the length of the spring Las =√√√√√1-2. You will use this equation in Sec. 6.5 of the experiment. For a slinky, the unstretched length is much shorter than the stretched length. Suppose that the fundamental standing wave is oscillating on a slinky. How does the period of the standing wave change as the lengthof the slinky is altered? A. It hardly changes B. It gets longer C. It gets shorter

A nylon rope of length 25m is under a tension of 1.3 × 104 N. The total mass of this rope is 2 kg. If a wave pulse starts at one end of this rope, find its speed. Calculate to one decimals?

A harmonre, sinusoidal wave propagates through a string. The wave is describe by y(x,t) = 12 sin(8x - 4t + π), where y and x are in meters and t in second. Calculate the speed of wave

A simple pendulum consists of a ball of mass 5.53 kg hanging from a uniform string of mass 0.0433 and length L. The period of oscilla- tion for the pendulum is 2.29 s. Determine the speed of a transverse wave in the string when the pendulum is station- ary and hangs vertically. The acceleration of gravity is 9.8 m/s² .
