## Homework Statement

An engraver uses a magnifying glass (f=9.5 cm) to examine some work. The image he sees is located 25 cm from his eye, which is his near point. A) what is the distance between the work and the magnifying glass? b) what is the angular magnification of the magnifying glass?

## Homework Equations

M= (1/f -1/di)N

1/di + 1/do = 1/f

## The Attempt at a Solution

A) 1/25 + 1/do= 1/9.5 do= 15.3 cm

b) m=(1/9.5 - 1/25) 25 M= 1.63

Can some one check/ correct my work, not sure if I'm using the correct formulas. Thank you.
