18. Waves & Sound Standing Wave Functions
2PRACTICE PROBLEM
A wave traveling along a string is totally reflected on a rigid boundary. The incident and reflected waves produce a standing wave pattern described by y(x,t) = (5 cm) sin [(π/4 rad/cm) x]sin[(30π rad/s)t]. Find the frequency of the incident and reflected traveling waves that make up this standing wave.
