Please answer the question correctly please. Thank you The drawing shows a crystalline slab (refractive index 1.646) with a rectangular cross section. A ray of light strikes the slab at anincident angle of 01 32.0°, enters the slab, and travels to point P. This slab is surrounded by a fluid with a refractive index n. What isthe maximum value of n such that total internal reflection occurs at point P?=Number iUnits01

An object is placed 11.9 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air.
