The wave equation is written down in an exam as $\frac { d ^ { 2 } y } { d x ^ { 2 } } = v ^ { 2 } \frac { d ^ { 2 } y } { d t ^ { 2 } }$ From dimensional considerations we see that A)v² should be replaced by $\frac { T } { \mu }$ . B)v² should be replaced by $\sqrt { \frac { T } { \mu } }$ . C)v² should be replaced by v. D)v² should be replaced by $\frac { 1 } { v }$ . E)v² should be replaced by $\frac { 1 } { v ^ { 2 } }$ .
