- Consider a image that is located 30 cm in front of a lens. It forms an upright image 7.5 cm from the lens. Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?arrow_forward2. In class, we discussed several different flow scenarios for which we can make enough assumptions to simplify the Navier-Stokes equations enough to solve them and obtain an exact solution.

Does the order matter and how do you determine what to put first. Question 4 AP, CHAPTER 13 FROM BASIC BIOMECHANICS 8TH EDITIONarrow_forwardThe drawing illustrates the dispersion of light by a prism. The prism is made from a certain type of glass, and has a cross section shaped like an equilateral triangle. The indices of refraction for the red and violet light in this type of glass are 1.649 and 1.694, respectively. The angle of incidence for both the red and violet light is 60.0°. Find the angles of refraction at which the (a) red and (b) violet rays emerge into the air from the prism.

What is the smallest possible refractive index for the liquid?arrow_forwardThe drawing shows a crystalline slab (refractive index 1.995) with a rectangular cross section. A ray of light strikes the slab at an incident angle of 01 = 35.0°, enters the slab, and travels to point P. This slab is surrounded by a fluid with a refractive index n. What is the maximum value of n such that total internal reflection occurs at point P? Ме Buarrow_forward
