2 cards from this section. Quick, good the night before a test.
What are the two components of a ray vector?
Think about how we describe direction and position.
What does the matrix T(d) represent?
Recall how distances relate to movement.
What does a ray vector represent?
Think about what characteristics a ray has.
True or False: The order of matrix multiplication does not affect the result.
Consider how changing the order might change your results.
A ray vector is initially at [2, 30 degrees]. It then travels 5 cm in a medium that causes its angle to adjust according to a specific refraction law. If the new angle is found to be 45 degrees, what is the final ray vector?
Examine how the medium alters the angle.
Given two matrices representing different optical elements, how would you combine them to find the final ray vector? Show the steps involved.
Think about the sequence of the transformation affecting ray travel.
