Question

Problem 5: The top picture shows a wave pulse on a string (string 1-blue) travelling to the right, where the string is attached to another string (string 2 - orange). The bottom picture shows the reflected wave some time later. If the tension on both strings is the same, a) [2 points) is string 2 more or less dense than string 1? Justify your answer b) 3 points) In which string will the wave travel faster? Justify your answer. were c) (2 points) Sketch what the acted wave would look like if the strings" den opposite of what you answered in part (a).

Answer 1

(a) string 2 is morse dense. renow, va F of string u= lincan We know, Tension ㅆ If u large then Vzo density. Here we see, no Va velocity wave in propagating orange part so, vzo hence langen Thans sming 1. (b) Again same Hone, v=J E IL . V a u is terass on stroing there The wave moves fasten ш seasoning 50 on (C) MaMa (As question) Now, Hesse Now There will be no neflected wave,
