JEE Mains · Physics · STD 12 - 9. Ray optics and optical instruments
Light ray incident along a vector \(\vec{AO}\) \((\vec{AO} = 2\hat{i}-3\hat{j})\) emerges out along vector \(\vec{OB}\) \((\vec{OB} = C\hat{i}-4\hat{j})\) as shown in the figure below. The value of \(C\) is ________.

- A \(1.6\)
- B \(0.16\)
- C \(11.6\)
- D \(16\)
Answer & Solution
Correct Answer
(A) \(1.6\)
Step-by-step Solution
Detailed explanation
From the given figure, the interface is horizontal and the normal is along the y-axis. The incident ray is along the vector \(\vec{AO} = 2\hat{i} - 3\hat{j}\). The angle of incidence \(\alpha\) is the angle between the incident ray and the normal.…
