Question 1.
What is a ray vector in the context of the Matrix Method?
Show hintHide hint
Think about how we express direction and position in 2D.
Question 2.
What does the translation matrix represent?
Show hintHide hint
Consider how far light moves without interacting with any surface.
3Question 3.
What does the matrix $T(d)$ represent?
- Refraction matrix
- Translation in free space
- Reflection matrix
Show hintHide hint
Consider what happens when light travels without interacting with anything.
4Question 4.
True or False: The system matrix is the product of individual matrices created from the optical elements in the correct order of light travel.
- True
- False
Show hintHide hint
Think about how you stack the transformations.
Question 5.
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.
Show hintHide hint
Remember the order of multiplication is crucial.
Question 6.
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.
