  1. Spherical mirror CoC centre of cusvatusu Sphsa Con vi CoC Rudius Apestue cou


  2. *Pole is that point on the mirror from which distance of objects can b easily calculated *Radius of curvature and Radius of aperture are two different terms *Center of curvature is the center of that sphere from mirror is cut *Principle axis is the line joint pole and center of curvature RAaue Paraxial rays t


  3. Q. Find distance x?


  4. *If the rays parallel to Principle axis and paraxial then the point where they meet or appears to meet is known as Focus of the Mirror facu light-ray concave mirror Focus Paraxial Rays Paraxial Rays . If Mirror is very small . If incident ray is making very small angle with normal of the mirror . If rays are very close to principle axis


  5. *Considering all rays as paraxial ON OP, IN IP, NC PC ma MN t-L = V = Image distance from pole U = Object from pole f focal length te


  6. Sign convention ne e- *Consider direction of usefull incident ray as positive and write U, V, F accordingly


  7. Sign convention ne e- *Consider direction of usefull incident ray as positive and write U, V, F accordingly


  8. Q. Find image distance in this case U =-30cm f-- 20cm Object is real, Mirror is concave By Applying mirror formula We get V- - 60cm Ro *Image formed on the left side of mirror so it is a real image
