A platinum wire that is 1.20 m long has a radius of 0.500 mm and is fixed at both ends. It'sfrequency is 512Hz and it has a wavelength of 2/3 its length. The density of platinum is 21.4 x10³ kg/m3. What is the tension in the wire?A 6.0-m wire with a mass of 50 g, is under tension. A transverse wave, for which the frequency is 810 Hz,the wavelength is 0.40 m, and the amplitude is 4.0 mm, is propagating on the wire. How long does ittake a crest of the wave to travel the length of the wire?The vertical displacement y(x,t) of a string stretched along the horizontal x-axis is given by y(x,t)= (6.00 mm) cos[(3.25 m-1)x - (7.22 rad/s)]. Identify the string's wavelength and period. Findthe speed of the wave. Find the maximum transverse speed for a point on the string.
