Acellist tunes the c string of her instrument to a fundamental frequency of 65.4 hz . the vibrating portion of the string is 0.600 m long and has a mass of 14.4 g .
what is μ, the mass per unit length of the string?
to determine the wave speed from purely kinematic quantities, you need to know the wavelength of the wave. what is the wavelength λ of the fundamental mode in the c string of the cello?

Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? a)\vec ein the +xdirection,\vec bin the +ydirection. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction b)\vec ein the -y direction,\vec bin the +x choose+ x direction- x direction+ y direction- y direction+ z direction- z direction c)\vec ein the +z direction,\vec bin the -x direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction d)\vec ein the +y direction,\vec bin the -z direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction
