Question: Two strings of different mass per unit length 1 and 2 are tied together and stretched with a tension F. A wave travels

Two strings of different mass per unit length µ₁ and µ₂ are tied together and stretched with a tension F. A wave travels along the string and passes the discontinuity in µ. Which of the following wave properties will be the same on both sides of the discontinuity, and which will change: speed of the wave; frequency; wavelength? Explain the physical reasoning behind each answer.
