An object is placed on the left of a converging lens at a distance that is less than the focal length of the lens. The image produced will be a) real and inverted. c) virtual and inverted. b) virtual and erect. d) real and erect.
What type of lens is a magnifying glass? a) converging d) cylindrical b) diverging e) plain c) spherical
How large does a \(5.0-\mathrm{mm}\) insect appear when viewed with a system of two identical lenses of focal length \(5.0 \mathrm{~cm}\) separated by a distance \(12 \mathrm{~cm}\) if the insect is \(10.0 \mathrm{~cm}\) from the first lens? Is the image real or virtual? Inverted or upright?
Suppose the near point of your eye is \(2.0 \cdot 10^{1} \mathrm{~cm}\) and the far point is infinity. If you put on -0.20 diopter spec tacles, what will be the range over which you will be able to see objects distinctly?
Two converging lenses with focal lengths \(5.00 \mathrm{~cm}\) and \(10.0 \mathrm{~cm}\), respectively, are placed \(30.0 \mathrm{~cm}\) apart. An object of height \(h=5.00 \mathrm{~cm}\) is placed \(10.0 \mathrm{~cm}\) to the left of the \(5.00-\mathrm{cm}\) lens. What will be the position and height of the final image produced by this lens system?
