The rope of the length 6 m is fixed to a vertical wall in the horizontal x-direction. We send one transverse pulse on a rope in a vertical +y direction towards and it returns back in 3 s. Which statement is correct? (i) The pulse returns in +y direction, the speed of the pulse is 2 m/s. (ii) The pulse returns in +y direction, the speed of the pulse is 4 m/s. (iii) The pulse returns in -y direction, the speed of the pulse is 2 m/s. (iv) The pulse returns in -y direction, the speed of the pulse is 4 m/s. (v) The pulse does not return.
