The left end of a long glass rod 7.00 c m in diameter has a convex hemispherical

Question

The left end of a long glass rod 7.00cm in diameter has a convex hemispherical surface 3.50cm in radius. The refractive index of the glass is 1.60. The glass rod is immersed in oil (n=1.45). An object placed to the left of the rod on the rod's axis is to be imaged 1.25m inside the rod. Part A How far from the left end of the rod must the object be located to form the image? ANSWER: s= ?

Explanation / Answer

Apply n1/p + n2/q = (n2-n1)/R

1.45/p + 1.6/1.25 = (1.6 - 1.45)/.035

p = .482 m (48.2 cm)
