Challenge Problems
Push your limits with challenges.
Question 1
For a system with two lenses and an additional space of 5 cm in between, how would you form the system matrix using individual matrices? Assume lens matrices are known.
💡 Hint: Remember the order of multiplication is crucial.
Question 2
If the ray input vector is \( \begin{bmatrix} 2 \ \ 15^{\circ} \end{bmatrix} \) and the total system matrix is \( M = \begin{bmatrix} 1 & 2 \ 0 & 1 \end{bmatrix} \), calculate the output ray vector.
💡 Hint: Matrix-vector multiplication will give you the new position and angle.
