6. [-/3 Points] DETAILS As shown below, light reflects off of the horizontal surface before striking the vertical surface (the interface between $\alpha$ & $\beta$) at the critical angle, $\theta_{crit} = 40^\circ$. The speed of light in material $\alpha$ is $6.00 \times 10^7$ m/s. Determine $\theta_i$ & the index of refraction in material $\beta$.
