Consider a wave function given by (x) = A sin kx, where k = 2/ and A

Consider a wave function given by ψ (x) = A sin kx, where k = 2π/λ and A is areal constant.
(a) For what values of x is there the highest probability of finding the particle described by this wave function? Explain.
(b) For which values of x is the probability zero? Explain.
