WebApr 7, 2024 · By using the formula below, the focal length f of the convex mirror can be calculated. F = R 2. Where, R-Radius of curvature. A mirror with a reflecting surface facing outwards is a Convex mirror, whereas a mirror with a reflecting surface facing inwards is a Concave mirror. Web1) A lens with focal distance of 30 cm is placed in front of an object, which is located at 1 m from it. Where is image of the object located? Answer: From the image position formula: …
Calculating Length, Radius & Frequency of Steel Guitar String
WebThe only way to make the focal length longer is making the mirror less curved. If we make it less curved, then the sphere which it is a part of, will also get bigger and hence keeping the center of curvature further than the focal point.
