From equation (1) & (2) If magnification m > 1,then image is magnified m = 1 ,image is of same size m < 1, image is diminished, Few Tips to Remember Sign Convention for Spherical Lens. Save my name, email, and website in this browser for the next time I comment. 5. Principal axis :Imaginary straight line passing through the two centres of curvature 3. The branch of physics in which the characteristics of light are studied is known as Optics.The concept that light is a wave had been discovered in ancient Greece in 5 BC to 3 BC.The reflection, diffusion, and vision were summarized by Euclid (300 -275 BC) in his book Optics. Candidates who are pursuing in Class 10 are advised to revise the notes from this post.

(i) Concave Mirror : It is a spherical mirror whose outer surface is polished and inner or (i) The incident ray, the reflected ray and the normal at the point of incidence, all lie in a same There are two types of lenses. 2. Reflection . Speed of light decreases as the beam of light travel from rarer medium to the denser medium. ii) The incident ray, the reflected ray and the normal to the mirror at . natur e. We shall try to understand in this Chapter the r eflection of light by spherical mirrors and refraction of light and their application in real life situations. diverged after refraction by a lens. → Refraction is bending of light when it enters obliquely from one transparent medium to another. Incident ray: The ray of light that falls on the reflecting surface is known as the incident ray. • Some examples of refraction → The bottom of swimming pool appears higher. Each of these surfaces forma part of sphere. Used to see large image of face as shaving mirror 3. h – is always +ve h´ – is +ve for virtual , –ve for Real. Light is a form of energy that … For example – Spoon  The curved surface of shinning spoon can be considered as curved mirror. myCBSEguide | CBSE Papers & NCERT Solutions. Plane Mirror : Plane mirror is a piece of glass whose one side is polished by using silver plane. The distance OF2 and OF1 is called as focal length, Image formation by a convex lens for various position of object, Sign Convention for Refraction by Spherical Lens, Similar to that of spherical mirror, only the difference is that all themeasurement are made from optical centre ‘O’. Few Basic Terms Related to Spherical Lens, 1. Free NCERT Books download for Class 10 Science Chapter 10 - Light Reflection and Refraction on Vedantu.com. Along with NCERT Solutions For Class 10 Science Chapter 10 Light Reflection and Refraction candidates can also find light reflection and refraction class 10 numericals questions in this article. These notes are prepared by our panel of highly experienced teachers keeping in mind the level of preparation needed by the students to prepare for Class 10 … All distance should be measured from pole (P); parallel to principal axis. Reflection of light by spherical Mirrors Mirrors, whose reflecting surface are curved inward or outward spherically are called spherical mirror. Class 10 Science notes on Chapter 10 Light Reflection and Refraction are also available for download in CBSE Guide website. Light: It is a form of energy which produces the sensation of sight. small area to produce high temperature. It is a common phenomenon that lens is used to magnify objects; thus, a formula for magnification is also taught. Optical Centre : The central point of lens is its optical centre (O).
