A) \[1.21\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[1.42\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[6.05\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[3.63\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: A
Solution :
Key Idea: The given standing wave has 2 segments. The given standing wave has shown in the figure. As length of one loop or segment is \[\frac{\lambda }{2}\], so length of 2 segments is \[2\left( \frac{\lambda }{2} \right)\] \[\therefore 2\frac{\lambda }{2}=1.21\,{\AA}\] \[\Rightarrow \lambda =1.21\,{\AA}\]You need to login to perform this action.
