WebApr 10, 2024 · An optical instrument is a device that processes light waves, either to enhance an image for just viewing purposes or to analyse and determine its whole characteristic properties. Commonly used examples of optical instruments include periscopes, microscopes, telescopes, and cameras.
Ray Optics and Optical Instruments Class 12 Notes CBSE
Webthat of a spherical lens is called its optical centre. The line joining the pole and the centre of curvature of the spherical mirror is known as the principal axis. In the case of spherical lenses, the principal axis is the line joining the optical centre with its principal focus as you will see later. 9.2.1 Sign convention WebLight waves can be bent and reflected to form new and sometimes altered images. Understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high powered telescopes. In this unit, let's learn about reflection, refraction, defects in the human eye and the lenses we use to correct them, and ... order a norcold recall kit
