What Is Optical Center?

Ray diagrams for the concave and convex lenses. But it is not possible to remember all the positions of images. For different positions of objects right now say the object is between focus and the center. Of curvature would you prefer to draw a ray diagram to know how the image would be or would you prefer a simple formula. That provides all the necessary details

Optical

About the image formed in the second one let’s find that formula here is a convex lens let us. Say the distance between optical center o and object is a called object distance denoted by u let us. Say the distance between the optical center o and the image formed is Oh a dash called image distance. Denoted by V we denote the focal length of the lens by F there is a relationship between these three quantities. Expressed as 1 by V

Optical Lens

Minus 1 by U is equal to 1 by F for all distances measured from the optical center. Oh, imagine that center as the origin of a Cartesian graph of all the distances. Measured in the direction of incident ray from the optical Center are positive. That is from o2 its right side is positive and the opposite direction is negative it is easier to remember. if you remember it is the same as the X Y coordinates concept of Cartesian graph ensure you put the right sign in the

Convex Lens

Can understand among these are the cornea a clear dome-like structure. Covering the iris or colored part of the eye the lens below it and the retina. Which aligns the back of the eye the retina consists of thin layers of light-sensitive tissue. This candle can help us understand how the eye captures images. And then send them to the brain first the candlelight passes. Through the cornea as it does its bent or refracted onto the lens as the light passes

Through the lens it’s bent a second time finally it arrives at the retina where an image from. This double-bending thought has reversed the image and turned it upside down. If that was the end of the story the world would always appear upside down. The image turned right-side up in the brain. Before that can happen the image needs to travel as impulses. Along the optic nerve and enter the brain’s occipital lobe.
