What would be the position an image formed by a Lens or a mirror if the object is not kept on the principal axis?
Geometrical optics is a branch of optics that studies the behavior of light as it travels through different media, such as air and water, and interacts with different surfaces, such as mirrors and lenses. It focuses on the principles of light ray propagation and image formation without taking into account the wave nature of light.
The image position in geometrical optics is determined by the intersection of the light rays that pass through the optical system. These rays are traced back from the object to the image, and the point where they converge is the position of the image. This can be calculated using the laws of reflection and refraction.
In geometrical optics, the principal axis refers to an imaginary line passing through the center of a lens or mirror. When an optical system does not have a principal axis, it means that the light rays are not parallel to this axis and may enter or exit the system at different angles. This can occur in curved mirrors or lenses with non-uniform surfaces.
In geometrical optics, the image distance is directly proportional to the object distance. This means that as the object distance increases, the image distance also increases, and vice versa. This relationship is known as the magnification equation and is an important concept in understanding image formation in optical systems.
Geometrical optics has numerous practical applications in everyday life, such as in the design of eyeglasses and contact lenses, telescopes and microscopes, and camera lenses. It is also used in the development of optical instruments for medical imaging, laser technology, and fiber optics communication systems.
