अवतल दर्पण द्वारा प्रतिबिम्ब निर्माण (गोलीय दर्पण द्वारा प्रतिबिम्ब निर्माण) अवतल दर्पण द्वारा प्रतिबिम्ब निर्माण :- गोलीय दर्पण से बने प्रतिबिम्ब की स्थिति, प्रकृति और आकार का निर्धारण करने के लिए वस्तु से आने वाली प्रकाश की दो किरणों पर विचार करना आवश्यक है। इसके लिए वस्तु से दर्पण पर आने वाली मुख्य…
Mirror Formula Mirror Formula :- Below figure shows the ray diagram of image formation by concave mirror considering three rays. It shows the image A′B′ (real in this case) of an object AB. In the above figure only three rays emanating from the point A are shown but actually an infinite number…
Relation Between Focal Length And Radius of Curvature Relation between focal length and radius of curvature :- Let C be the center of curvature of the mirror. Consider a ray parallel to the principal axis striking the mirror at M. Then CM will be perpendicular to the mirror at M. Let θ be the…

Image formed by plane mirror is ? Image formed by Plane Mirror :- The image formed by plane mirror is always virtual, upright, and of the same shape and size as the object. The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to…
Image formed by convex mirror (Image formation by spherical mirror) Since focus(F) in a convex mirror and center of curvature(C) are located behind the mirror, so the object can have only two positions, one at an infinite distance and the other between the pole and infinity of the mirror. (a) When the object…
Image formation by concave mirror (Image formation by spherical mirror) To determine the position, nature and size of the image formed by a spherical mirror, it is necessary to consider the two rays of light coming from the object. For this, a ray parallel to the principal axis coming from the object to…
Ray Optics Ray optics is that part of optics which studies the motion of light by considering it as a ‘ray’. According to the assumption of ray optics, as long as light travels in a homogeneous medium, its path is a straight line. Where two mediums meet, the light rays are bent. Light…
