Consider a transverse periodic (sinusoidal) wave passing through a very long string of mass density 0.250 kg/m. The wave function for this wave is found to be:  y (x,t) = (0.125 m) cos [(1.10 rad/m) x - (15.0 rad/s) t]   From the equation find the following quantities 1. Direction of th oscillation of the medium (i.e. which axis) 2. Direction of the motion of the wave (i.e. which axis, and ij the positive or negative direction) 3. Speed of the wave  4. Tension of the string 5. Average power P av delivered by the wave

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
