Fun Lens Makers Formula Derivation Class 12
Equation vii is known as.
Lens makers formula derivation class 12. In this video I will make you understand the derivation of famous lens Makers formula which is important for class 12 examsThe lens makers equation is a f. Class 12 Physics Ray Optics Optical Instruments. Consider a thin convex lens of focal length f RI n placed in air as shown in fig.
Equating eq 1 and 2 we get. Refraction at curved surfaces. This was the derivation of Lens formula.
A lens maker formula may be defined as the formula which gives the relationship for calc. Stay tuned with BYJUS and learn various other Physics related topics. When s is infinity in 12 the value of s will be the focal length f.
It is a relation between the focal length of a lens to the refractive index of its material and the radii of curvature of its two surfaces. This formula connects the focal length of a lens to its refractive index. From equations iii and iv we obtain.
CD 2 R 2. O Luminous point object on the principle axis. Dividing both the sides by uvf we get.
The image I 1 acts as a virtual object for the second surface that forms the image at I. The above listed were a few important derivations of CBSE class 12 physics that are most likely to be asked in the coming board exams. OB-u OBv and OFf.
