Ray Optics Flashcards
What is the Cartesian sign convention?
The Cartesian sign convention is a method used in geometrical optics to assign signs to distances and focal lengths for mirrors and lenses.
What do the symbols u, v, and f represent in the Cartesian sign convention?
In the Cartesian sign convention, u represents the distance of the object, v represents the distance of the image, and f represents the focal length.
Why is a sign convention necessary in geometrical optics?
A sign convention is necessary to ensure consistent application of formulas across different cases involving mirrors and lenses.
What is the most convenient sign convention in geometrical optics?
The most convenient sign convention in geometrical optics is the Cartesian sign convention, as it is analogous to coordinate geometry.
What happens to the numerical values of u, v, and f for a spherical mirror or lens?
The numerical values of u, v, and f will differ based on the position of the object and the type of mirror or lens used.
