Problem 21P
The vertical displacement of a wave on a string is described by the equation y(x, t) = A sin(Bx − Ct), in which A, B, and C are positive constants, (a) Does this wave propagate in the positive or negative x direction? (b) What is the wavelength of this wave? (c) What is the frequency of this wave? (d) What is the smallest positive value of x where the displacement of this wave is zero at t = 0?
