A) 0.6 cm
B) 12 cm
C) 60 cm
D) 120 cm
Correct Answer: B
Solution :
The distance between two points i.e. path difference between them \[\Delta =\frac{\lambda }{2\pi }\times \varphi =\frac{\lambda }{2\pi }\times \frac{\pi }{3}=\frac{\lambda }{6}=\frac{v}{6n}\] \[(\,\because \,\,v=n\lambda )\] Þ \[\Delta =\frac{360}{6\times 500}=0.12\,m=12\,cm\]You need to login to perform this action.
