What Will Be The Image Distance If Object Is Situated At 40 Cm? Answer: Since focal length of concave mirror given is 20cm l. Object is at 40cm distance which means it is at centre of curvature. hence, image will be formed of same size and at centre focus only but real and inverted. When
What Is The Relation Between Object Distance And Focal Length? As the object distance approaches one focal length, the image distance and image height approaches infinity. Finally, when the object distance is equal to exactly one focal length, there is no image. What is the relationship between distance of object U distance of image V
What Is The Relationship Between Focal Length And Magnification? The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification. How do you calculate focal length from magnification? Focal length = (Object distance /
