Sign Convention for Spherical Lenses
Sign convention for spherical lenses is a set of rules used to determine the direction of light rays passing through a lens. It helps in understanding the behavior of light rays and image formation. The sign convention consists of the following rules:
- Principal Axis: The principal axis is the line passing through the center of the lens perpendicular to its surface. It is considered the positive direction.
- Focal Length: Focal length is positive for converging lenses and negative for diverging lenses. It is measured from the optical center of the lens to the focal point on the principal axis.
- Object Distance (u): Object distance is positive when the object is on the same side as the incident light and negative when it is on the opposite side. It is measured from the object to the optical center of the lens.
- Image Distance (v): Image distance is positive when the image is formed on the same side as the incident light and negative when it is on the opposite side. It is measured from the image to the optical center of the lens.
- Height (h): Height is positive when the object or image is above the principal axis and negative when it is below the principal axis.
By following these sign conventions, we can determine the nature of the image formed by a spherical lens and calculate its characteristics accurately.
