Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Examine how the medium alters the angle.
Question 2
Given two matrices representing different optical elements, how would you combine them to find the final ray vector? Show the steps involved.
💡 Hint: Think about the sequence of the transformation affecting ray travel.
