Question
A small pulse travelling with speed v in a string is shown at t=0, moving towards free end. Which of these is notcorrectly matched.
(i) $t = \frac{L}{v}$ (P) 
(ii) $t = \frac{2L}{v}$ (Q) 
(iii) $t = \frac{3L}{v}$ (R) 
Options
A.(i)
B.(ii)
C.(iii)
D.None of these
Solution
Sol. In option (ii), the wave will become inverted when it gets reflected from fixed end at the left.
