CloudLabs Spherical mirrors
Read full descriptionHide full description
This simulation recreates an optical table with a concave and a convex mirror, the goal is to find the focal length, the radius of the curvature and determine if the image is inverted or not. In the development of the practice, each of the mirrors can be placed on the optical table and two objects can be used to observe both the image that is formed, as well as its size, as the distance between the object and the mirror is varied.
