Image will be real and inverted and will be of size 14 cm. Suggest Corrections 7 Similar questions Q. 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 fo...
Hint: We need to understand the relation between the size of an object, its distance from mirror and the focal length of the concave mirror with the image formed by the mirror and the properties of the image such as the size, position and nature.Complete ans...
We show that measured optical transmittance of an ultra thin gas depends on the detector size. To this end we conducted an experiment that compares transmittances measured in parallel with a pair of detectors with different diameters ranging from 2 to 20
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....
