Lecture No 2 Resolution And Magnification

Magnification Magnification is the degree to which an image is enlarged compared to the actual size of the object. Definition: Magnification is the ratio of the image size to the real size of the object. Formula: \text{Magnification} = \frac{\text{Size of image}}{\text{Actual size of object}} Key points: • It tells you how big the image appears. • Higher magnification makes objects look larger. • Magnification alone does not guarantee clarity. Example: If a microscope magnifies an object 100×, the image appears 100 times larger than its real size. ⸻ Resolution Resolution is the ability of an optical instrument to distinguish two very close objects as separate and distinct. Definition: Resolution is the minimum distance between two points that can still be seen as separate. Key points: • It determines clarity and detail of the image. • Higher resolution means sharper and clearer images. • Poor resolution causes images to look blurred, even at high magnification. Example: Two closely spaced dots can only be seen separately if the microscope has good resolution.
