need help please

a double convex lens has a radio of curvatures R1=14cm and R2= 34cm is in a basket. the lens made of glass with an index refraction n=1.63,

what is the focal lenght
express answer in cm to two decimal places.
hint( sign must be properly assigned to each radii)

not radio but radii*

Answer 1

Answer #1

$conven 1. = 14cm Solution. For double lens R,= R2 = -34cum refractive Inden of glass of fons (n) = 1.63 By using lens maker f$

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 8.00 mm , 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...
