13.4 Images Formed by Lenses
AdvancedMCQGraphicalMathematicalConceptual17.5k
A quantitative Cartesian coordinate graph plotting vertical axis labeled 1/di in units of m^-1 from -3.0 to +5.0, and horizontal axis labeled 1/do in units of m^-1 from 0.0 to 6.0. A straight solid line with a slope of -1.0 passes through the vertical intercept at (0, 4.0) and the horizontal intercept at (4.0, 0). Data points are shown along the line at (1.0, 3.0), (2.0, 2.0), (3.0, 1.0), and (5.0, -1.0). Grid lines are drawn every 1.0 unit on both axes. No other labels, lines, text, or axes appear.
Graph of 1/di versus 1/do for the thin lens.
A student conducts an experiment to determine the properties of an unknown thin spherical lens by measuring the image distance \(d_i\) for various object distances \(d_o\). The student plots \(\dfrac{1}{d_i}\) as a function of \(\dfrac{1}{d_o}\), producing the best-fit line shown in the graph. Which of the following claims correctly identifies the type of lens, its focal length, and the nature of the image formed when an object is placed at \(d_o = 0.20\text{ m}\)?
