Ray diagram showing refraction across three parallel media.
Ray diagram showing refraction across three parallel media.
A monochromatic light ray travels through three parallel, transparent media with smooth planar boundaries, as shown in the diagram. The ray enters Medium 2 from Medium 1 and subsequently enters Medium 3 from Medium 2. The ray makes angles of \(\theta_1 = 30^\circ\), \(\theta_2 = 60^\circ\), and \(\theta_3 = 45^\circ\) with the horizontal interface boundaries in Media 1, 2, and 3, respectively. Which of the following correctly ranks the speed of light \(v_1\), \(v_2\), and \(v_3\) in the three media?
