Which statement is false? O A traveling wave is described by y(x.t) = A sin(kx + wt + (]. If kx and wt have the same sign, the wave travels in the positive x-direction. O A traveling wave is described by y(x t) = A sin(kx + wt + ], where whatever multiplies x is k = 2n/2, whatever multiplies t is w = 2n/T = 2nf. and v = Af = w/k = speed. O) When two or more waves interfere, the resulting displacement is equal to the vector sum of the individual displacements. O The relationship v = Af holds true for any periodic wave.A string is clamped at both ends and plucked so it vibrates in a standing wave between two extreme positions as shown by the dashed lines below. If the string has length L and the frequency of oscillation of this mode is f, the speed of the waves on that string is Length L OfL O 3FL O (3/2 )L O (2/3) f LWhat is the relationship between the energy of a wave and its amplitude? O The energy of a wave is inversely proportional to the square of the wave amplitude. O The energy of a wave is proportional to the square of the wave amplitude. O There exists no relationship between the energy of a wave and its amplitude? O The energy of a wave is proportional to the wave amplitude. The energy of a wave is inversely proportional to the wave amplitude
