(b) The minus sign is customarily ignored. Reflect: Eq.(25.4) gives Eq.(25.4) assumes that that this is only approximately the case here. 25.34. Set Up: For each lens, The image formed by the objective serves as the object for the eyepiece. Solve: (a) (b) and (c) Eq.(25.4) gives Eq.(25.4) omits the minus sign and is only approximately correct. 25.35. Set Up: The object for the eyepiece is at its focal point and is the image formed by the objective. Therefore, where L is the length of the microscope. Solve: (a) (b) Reflect: When for example, and The approximation that leads to Eq.(25.4) is fairly accurate. 25.36. Set Up: Since the image formed by the eyepiece is at infinity, the angular magnification for the eyepiece is The overall angular magnification of the microscope is The image formed by the objective is the object for the eyepiece and is at the focal point of the eyepiece. Solve: (a) The image formed by the objective is from the lens. gives (b) (c) Eq.(25.4) gives Eq.(25.4) omits the minus sign and is only approximately correct.
