The focal length of a concave mirror is30cm.Find the position of the object in front of the mirror,so that the image is there times the size of the objects. View Solution You are given a concave mirror of focal length 30 cm. How can you form a real image of the size of the object...
In theorem 16 of the pseudo-Euclidean treatise Catoptrica the position of the image of a point reflected in a plane mirror is found as the intersection of the ray between eye and mirror and the perpendicular from the object to the plane of the mirror. 1 In Fig. 1, which is taken from...
and reliability by digitizing a spot image of an astigmatism shape, which is generated from a half mirror, calculating the second moment of area against a short axis and a long axis and deriving their ratio, and executing a position adjustment in the optical axis direction of a concave lens....
To solve the problem, we need to find the position of the object in front of a concave mirror such that the image formed is three times the size of the object. Given the focal length of the concave mirror is 30 cm, we can follow these steps:<st
