A) \[{{y}_{B}}={{y}_{G}}\]
B) \[{{y}_{B}}>{{y}_{G}}\]
C) \[{{y}_{G}}>{{y}_{\operatorname{B}}}\]
D) \[{{y}_{B}}/{{y}_{G}}=550/460\]
Correct Answer: C
Solution :
| Option [c] is correct |
| Explanation: \[{{y}_{n}}=n\lambda \operatorname{D}/d\] |
| So, \[{{y}_{n}}\propto \lambda \] |
| Since \[{{\lambda }_{\operatorname{G}}}>{{\lambda }_{\operatorname{B}}}\] |
| \[\therefore \] \[{{\phi }_{G}}>{{y}_{B}}\] |
