Question

007 10.0 points The bellows of an adjustable camera can be extended so that the largest distance from the lens to the film is 1.61 times the focal length. If the focal length of the lens is 4.85 cm, what is the distance from the closcst objeet that can be sharply focused on the film Answer in units of em 008 10.0 points A physics student placcs an objeet 6.0em from a converging lens of focal length 9.0 What is the magnitude of the magnification of the image produced? 1. IM 15 2. IMI 0. 3. IM1-3.0 4. IMI-2.0 5. IM 3.6 009 10.0 points The magnification produced by a couverging lens is found to be -2.44 for an object placed 0.187 m from the lens. Answer in umits of m.

Explanation / Answer

Q.8) 1/v - 1/u = 1/f

1/v = (1/9+1/6) then V = 54/15

Magnification = -v/u

M = -(54/15)/(-6) = 0.6

Option 2 is correct answer.
