An object is placed 24.0 cm to the left of a diverging lens(f = -5.89 cm). A concave mirror (f = 16.8 cm) isplaced 36.7 cm to the right of the lens to form an image of thefirst image formed by the lens. Find the final image distance, measured relative to the mirror.
A light ray enters a glass slab at point A at an angle of 57.6° with respect to the surface normal and then undergoes total internal reflection at point B. What minimum value for the index of refraction of the glass can be inferred from this?
