Best Lens Maker Formula Class 10
Example 103 - A concave lens has focal length of 15 cm.
Lens maker formula class 10. The focal length of a lens defines its ability to converge or diverge the light rays. This is because the separation between the two refracting surfaces will also be small. Check the limitations of the lens makers formula to.
The medium on either side of the lens needs to be the same. This was the derivation of Lens formula. Convex lens when real image is formed Consider a convex lens of focal length f.
OB-u OBv and OFf. The lens needs to be thin. Live Classes Video Lectures Test Series Lecturewise notes topicwise DPP dynamic Exercise and much more on Physicswallah AppDownload the App from Google.
This formula only works for thin lenses. So we can conclude that a convex lens need not necessarily be a converging and a concave lens diverging. The lens maker formula is utilized to create a lens with a defined focal length.
Using the formula for refraction at a single spherical surface we can say that For the first surface Therefore we can say that Where μ is the refractive index of the material. Limitations of Lens Makers Formula. Refraction at curved surfaces.
