Question
This mastering physics question can change my grade from a C to a B please. The left end of a long glass rod 8.00cm in diameter and with an index of refraction of 1.60 is ground and polished to a convex hemispherical surface with a radius of 4.00cm . An object in the form of an arrow 1.30mm tall, at right angles to the axis of the rod, is located on the axis 20.5cm to the left of the vertex of the convex surface. Find the position of the image of the arrow formed by paraxial rays incident on the convex surface. Find the height of the image formed by paraxial rays incident on the convex surface. I only have 2 attempts leftExplanation / Answer
1/20.0 +1.6/s' = (1.6-1)/4 0.05 + 1.6/s' = 0.15 1.6/s' = 0.1 s' = 16cm (agreed) As far as I konw: Magntifcation = image height/object height = image distance/object diatance = s'/s y'/1.7 = 16/20 y' = 1.36mm
