We are given a concave mirror which has a focal length of 18 cm. An object of height 7 cm is placed in front of the concave mirror such that it is 27 cm away from the mirror.We know that the image formed by this object, if real can be captured on...
An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. At what distance from the mirror should a screen be placed so that a sharp focused image can be obtained? Find the size and the nature of the image. Q. An object of size 7.0 cm i...
A flat concave cylindrical lens consists of one plane and one concave cylindrical surface, with a negative focal length. It is commonly used to concentrate parallel or divergent light beams onto a line or change the aspect ratio of an image....
The upper border is evenly convex, the lower border concave. The pelvis may be rounded or oval, square or elongated. Quite often the pelves are not of the same type or of the same size on both sides. The difference in size between different individuals is also considerable and bears no ...
