WebDec 16, 2024 · To determine the overall resistance of this system, use this formula: 1/R (p) = 1/R (1) + 1/R (2) = 1/ (12Ω) + 1/ (4Ω) = (1 + 3)/ (12Ω) –> R (p) = 3Ω Question 5 A scientist looks through a microscope with two thin lenses with m1 = 10 and m2 = 40. What is the overall magnification of this microscope? A. 0.25 B. 30 C. 50 D. 400 Answer 5 WebThin Lens Equation Where: DI= Distance between the image and the center of the lens DO= Distance between the object and the center of the lens F = Focal length NOTE: The sign convention used is as follows: if DIis negative then the image produced is a virtual image on the same side of the lens as the object itself. Object Distance (DO):

WebMar 22, 2014 · The equation is simple and always works, 1/f = 1/0 + 1/i. 1) object (o) is always +. 2) For mirrors, images (i) and focal points (f) are always + when they are on the same side of o. (just think: mirrors reflect) 3) For lenses, i and f are always + when they are on the other side of o.
