Reflection and Refraction

Paid Ray optics and geometrical optics it is a branch of optics light is considered as area which travels in a straight line it is the state that for each and every object there is any match schedule with the phenomenon of refraction and reflection of light by ordinary geometrical method deflection election is a phenomenon of change in the path of light after indicating on the mountain separating two media with and without any change in the medium reflection off the light that returning back off the light in the same medium from which it has come after striking a surface is called reflection of light the angle of incidence is equal to the angle of reflection are the incident ray reflected ray and the normal lie on the same plane in plane Mila rainmeter image formed is always virtual electrical to the size as that of the object and the same distance behind the mirror as the object in front of the mirror image in a plane mirror is always you literally inverted a type of mirror whose reflecting surface is a part of hollow sphere is spherical mirrors are the two types convex concave spherical mirror convex spherical mirror and all measurements among the direction of indicate re will be positive ana positive and negative all the measurement for the direction of book the principal Axis are taken as positive and below the principal Axis are taken as negative for a real object new is negative whereas v is a negative for the real image and positive for virtual image mirror formula is a reflection between focal length of a mirror distance of object and image from the mirror where is equal to focal length you equals to distance of object from mirror and because distance of image from the mirror.
