The equation of a certain traveling transverse wave is y1 = 2 cos (200nt - 0.05nx) where x and ·y are in cm and t is the time in seconds. Find the transverse velocity of the vibration in y-direction, as a function of time. Hint: Take the partial derivative with respect to t, treating x as a constant. a. Uy = -400 n sin 2n(l OOt - 0.025x) c. Uy = -0.05 sin 2n(l00t - 0.025x) b. Uy = -200 sin 2n(l OOt - 0.025x) d. Uy = -0.10 n sin 2n(l OOt - 0.025x)

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.
