Some important point of optical system

Optics light Minions of reflect in India few is immersed in a medium of refractive index you then when alliances taken in another medium the focal length changes to FM which is given by the medium in the air the focal length of lens is given by and the nature reserved linear magnification of a lens is defined as the ratio of height of image formed by a lens and the height of the object when image is virtual erect and the forms on the same side of objects is cancelled convex lens give positive linear magnification power virtual image and negative linear magnification for DL image it is the relation between focal length and the lens distance of object and image from optical centre of the lens has got the property binding the indication light towards the best ways to save the position of transmission medium bounded by two plane faces included to each other at a suitable angle the phenomena of petting of light into its component colours on passing through a reflecting vitamin known as dispersion angular dispersion produced by a prism for white light is difference in the angle of depression of two extreme colours that is violet and red power of prism is defined as the ratio of angular distribution to the mean by vation produced by prism so it is a phenomenon which light is different from the past due to the interaction with the particles of the medium through which it passes it is said that the intensity of the light of wavelength present it is scattered light it is inversely proportional to the 4th power provided the size of catering particle are much smaller than new basically the sky and the radius of Sun at sunset could be explained by this URL or angular dispersion produced by prism for white light it is reference in the angle of deviation for an extreme colleges wallet Android
