An object is located in water $30 \mathrm{cm}$ from the vertex of a convex surface made of Plexiglas with a radius of curvature of $80 \mathrm{cm} .$ Where does the image form by refraction and what is its magnification? $n_{\text {water }}=4 / 3$ and $n_{\text {Plexiglas }}=1.65$

Key Concepts

Refraction

Refraction is the bending of light as it passes from one medium to another with a different optical density. This change in direction is governed by Snell's law and is fundamental to understanding how light behaves at interfaces between different materials.

Index of Refraction

The index of refraction quantifies how much a ray of light slows down in a medium compared to its speed in vacuum. It plays a critical role in determining the degree of bending as light passes from one medium to another and is essential for predicting image formation.

Spherical Refracting Surface

A spherical refracting surface is a curved interface between two media with different indices of refraction. The curvature, characterized by the radius of curvature, along with the indices of the media, is used in the refraction formula to locate the image formed by the surface.

Image Formation and Magnification in Optics

Image formation in optical systems involves determining the location and nature of the image produced when light is refracted at an interface. Magnification refers to the ratio of the image size to the object size and is determined by the geometry of the setup, including object distance, image distance, and the refractive properties of the media.

Sign Conventions in Optical Interfaces

Sign conventions are critical when applying the formulas for refraction at curved surfaces. They dictate the positive or negative assignment to distances (object, image, radius of curvature) and ensure that the mathematical relationships accurately describe the physical situation in optical systems.
