A) 500 V
B) 1000 V
C) 2000 V
D) 50 V
Correct Answer: D
Solution :
For constructive interference, path difference \[=n\lambda \] From the given figure, path difference = MP+PN = 2d cos i \[\therefore \] \[2d\,\cos i=n\lambda \Rightarrow \lambda =\frac{\sqrt{3}}{n}\overset{o}{\mathop{A}}\,\] Also \[\lambda =\sqrt{\frac{150}{V}}\overset{o}{\mathop{A}}\,\] \[\therefore \,\,\,{{\left( \frac{\sqrt{3}}{n} \right)}^{2}}=\frac{150}{V}\Rightarrow V=50\,{{n}^{2}}\] For n = 1, V = 50 voltYou need to login to perform this action.
