Homework Statement A magnifier has a magnification of 9× How far from the lens should an object be held so that its image is seen at the near-point distance of 25 cm? Assume that your eye is immediately behind the lens. Express your answer to two significant figures and include the...

Yea i noticed it later. so ended up with . (6000/37) - mm which comes out to 162 mm. so its 162mm/s

so i got 1/f = 1/object + 1/ image = 1/160 = 1/12000-mm + 1/image =(37/6000)-mm is the image distance so far am i correct?

The only equation i came out with was 1/f = (1/d object) + (1d image)

Unfortunately at the moment I do not. Currently on khan academy after the Optics section maybe I will. I apologize

Firsts of this is not my problem I don't even take physics but it is my girlfriends. She doesn't know how to get the answer an neither do I. I took some physics but not enough for this. 1. Homework Statement A sports photographer has a 160-mm-focal-length lens on his camera. The photographer...

Homework Statement ∫x2(√2+x) Homework Equations ∫f(x) from a to b = f'(b) - f'(a) and substitution rule The Attempt at a Solution [/B] I decided to make u=√(2+x), du= 1/2√(2+x) and when solving dx, i got dx= 2√(2+x) du. Substituting and then simplifying, I managed to get ∫2(x^2)u^2 du. But i...
