To understand the standard formula for a sinusoidal traveling wave. one formula for a wave with a y displacement (e. g., of a string) traveling in the x direction is y(x, t)=asin(kx−ωt). all the questions in this problem refer to this formula and to the wave it describes. a) which are independent variables? b) which are parameters that determine the characteristics ofthe wave? c) what is the phase phi(x, t) of the wave? d) what is the wavelength lambda of the wave? e) what is the period tof this wave? f) what is the speed of propagation v of this wave?
