By mirror formula, findthe size nature and position of image formed when an object of size 1 cm is placed at a distance of 15from a fro from a concave mirror of focal length 10cm cm from a concave mirror of focal length in centimetre from a concave mirror of, why can't we write mirror formula as f = v + u, In which part of mirror we will take positive and negative sign?In Radius of curvature, R = 2f = 2 x (-7.5) = 15cm Also, it can be determined the curvature ratio of the lens.

All the distances parallel to the principal axis are measured from the pole (p) of the mirror. Image distance is the distance of the image from the pole of the mirror and it is denoted by the letter v. And focal length is the distance of the principal focus from the pole of the mirror. Concave and convex mirror, in magnification topic numerical problem solve, a) The image formed in front of the concave mirror is real, so m is negative, Want a call from us give your mobile number below, For any content/service related issues please contact on this number. Distances measured above the principal axis are positive. The magnification image formed by a spherical mirror is given by the height of image divided by the height of the object. As m = -v/u or -3 = -v/-10 the above answer is wrong pls check it, A person has a rectangular sheet of metal.He has to make cylindrical vessel whose both circular ends are closed.When he minimizes the wastage of the sheet,then what is the ratio of the wasted sheet to the utilised sheet? Asked by Topperlearning User | 21st Jul, 2017, 11:06: AM. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. 2) A lens forms an image at 25 cm from it, where the real object is placed at 1 m. What are the focal length of the lens and its curvature radius? Object distance is the distance of the object from the pole of the mirror; denoted by the letter u. a) The image formed in front of the concave mirror is real, so m is negative, Following is the table explaining concepts related to mirror: Here are some examples of spherical mirror formula problems: 1) A lens having a focal distance of 30 cm is placed in front of an object, which is located at 1 m from it. (2) . concave and convex mirrors and spherical mirrors. e. All the distances … Derivations for a mirror formula with a ray diagram. Expert Answer: By mirror formula, we have v = - u, i.e. (3) . c. The object is always placed on the left side of the mirror which implies that light falling from the object on the mirror is on the left-hand side.
