The Cartesian sign convention will be used in this course. 2) The origin of the Cartesian coordinate system … This sign convention is known as New Cartesian Sign Convention. Hellow every one I am a subscriber of vedantu and I am going to make live lectures videos on ytb. Either form can be used with positive or negative lenses and predicts the formation of … Refer to the diagram for clear visualization. According to the new Cartesian sign convention for the refraction of light through the concave and convex lens: All distances are measured from the optical centre of the lens. An orientation chooses which of the two half-lines determined by O is the positive, and which is negative; we then say that the line "is oriented" (or "points") from the negative half towards the positive half. The sign is taken as positive for a real object or image distance.A form using the Cartesian sign convention is often used in more advanced texts .If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. Sign Convention for Spherical Mirror: Cartesian Sign Convention: In the case of spherical mirror all signs are taken from Pole of the spherical mirror, which is often called origin or origin point. A form using the Cartesian sign convention is often used in more advanced texts because of advantages with multiple-lens systems and more complex optical instruments. Distances measured in the direction opposite to the direction of incident light are considered negative. In this video we explained Cartesian sign convention with easy trick. A common Gaussian form of the lens equation is shown below. Then each point P of the line can be specified by its distance from O, taken with a + or − sign depending on which half-line contains P.

Sign Conventions. Choosing a Cartesian coordinate system for a one-dimensional space—that is, for a straight line—involves choosing a point O of the line (the origin), a unit of length, and an orientation for the line. New Cartesian Sign Convention is used to avoid confusion in understanding the ray directions. This is NOT the same as used in Halliday and Resnick, but is used in many specialist optics textbooks. Correct answer(a) The Cartesian convention emphasizes the point of view which looks at a lens as changing . In this video we explained Cartesian sign convention with easy trick.#sign #cartesian #rayopticSHARE,SUPPORT,SUBSCRIBE!! This is the form used in most introductory textbooks. This means the sign is always taken as −(negative) in front of a spherical mirror. For the measurement of all the distances, the optical center of the lens is considered. Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis. In this case we have:-1) Light initially propagates from left to right. The following sign conventions are used by Cartesian: (1) All distances are measured from the pole of the mirror (in the case of the lens from the optic center).
