WebProblem 1.8 Two waves on a string are given by the following functions: y 1 (x, t) = 4cos (20 t − 30 x) (cm) y 2 (x, t) = − 4cos (20 t + 30 x) (cm) where x is in centimeters. The waves are said to interfere constructively when their superposition y s = y 1 + y 2 is a maximum, and they interfere destructively when y s is a minimum. WebProblem 1.7 A wave traveling along a string in the +x-direction is given by y. 1 (x,t)=Acos(ωt −βx), where x = 0 is the end of the string, which is tied rigidly to a wall, as shown
