Question

Exercise 34.32 The crystalline lens of the human eye is a double- convex lens made of material having an index of refraction of 1.44 (although this varies). Its focal length in air is about 8.00mm , which also varies. We shall assume that the radii of curvature of its two surfaces have the same magnitude. (Note: The results obtained in the parts A, B and C are not strictly accurate, because the lens is embedded in fluids having refractive indexes different from that of air.) Incorrect; Try Again; 4 attempts remaining Part B IF an object 10.0cm tall is placed 27.0cm from the eye lens, where would the lens focus it? S?=0.824 mm Part C How tall would the image be?|y?|=0.305 mm

Explanation / Answer

Given that

f=8 mm

h=10 cm=100 mm

u=-27 cm=-270 mm

Using lens formula=>(1/f)=(1/v)-(1/u) => v=8.24 mm

Also, Magnification=h'/h=-v/u =>|h'|=|(v/u)*h|=3.05
