Now on entering the glass medium this ray bends towards the normal NN’ that is light ray, After getting refracted this ray now travels through the glass slab and at point, Emergent ray is parallel to incident ray because the extent of bending of the ray of light at the opposite parallel faces which are. Now a question arises what happens when light travels from one medium to another with different densities for example from air to glass. (i) A film formed by one drop of sassafras oil, on a horizontal surface of a flint glass block, is viewed by reflected light. (a) Images formed by mirrors are always virtual and erect. A ray of light that strikes a plane mirror PQ at an angle of incidence of 30, is reflected from the plane … Laws of refraction of light: The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane. Refraction is due to change in the speed of light as it enters from one transparent medium to another. Made by: SHREYAANS M. NAHATA PODAR INTERNATIONAL SCHOOL, JALGAON [10TH RUBY 29] 1 2. Power of a convex lens is positive and that of a concave lens is negative. Aperture of the mirror: - Portion of the mirror from which reflection of light actually takes place is called the aperture of the mirror. I like it. The distance between the pole and the principal focus of a spherical mirror is called the focal length. Login. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Similarly in figure 1 (b) several rays of light parallel to the principal axis are falling on a concave lens. Reflected:- If an object sends back light rays falling on its surface then it is said to have reflected the light, The process of sending back light rays which falls on the surface of an object is called. It is represented by the letter C. Please note that the center of curvature is not a part of the mirror. and this happens because they reflects lights which falls on them from a luminous object like sun, lamp etc. Physics. A lens has two principal foci. NCERT Book Class 10 Science Chapter 10 Light – Reflection and Refraction In case of convex mirror rays get reflected at the reflecting surface of the mirror and these reflected rays appear to come from point F on the principle axis and this point F is called principle focus of convex mirror. The object is always placed to the left of the mirror. It is given by, If medium 1 is vacuum or air, then the refractive index of medium 2 is considered with respect to vacuum. Refraction of light through spherical lens class 10 science NCERT. These MCQ Quiz includes almost all the intext questions as well as exercises questions also. All right reserved. (i) A ray of light passes from water to air. Light - Reflection and Refraction. Convex mirrors are used as rear view mirrors in automobiles to see the traffic at back side as they give erect images and also highly diminished one giving the wide field view of traffic behind. • Some examples of refraction → The bottom of swimming pool appears higher. Center of curvature: - The reflecting surface of a spherical mirror forms a part of a sphere. Principle axis: - Straight line passing through the pole and the center of curvature of a spherical mirror is called principle axis of the mirror. Convex mirrors have its focus and center of curvature behind it and no light can go behind the convex mirror and all the rays that we show behind the convex mirror are virtual and no ray actually passes through the focus and center of curvature of the convex mirror. In order to construct a ray diagram to find out the position, nature and size of image formed by convex mirror we should remember following path of rays of light. However, it lies behind the mirror in case of a convex mirror as shown above in the figure 2. A film of the same oil on crown glass appears dark as its outer margin. It includes all the topics given in NCERT class 10 Science text book. Answer: Given, refractive index of glass (n g) = 1.50. Distances measured perpendicular to and below the principal axis (along -y-axis) are taken as negative. The SI unit of power of a lens is ‘diopter’. Another way to prevent getting this page in the future is to use Privacy Pass. (a) State Snell’s law of refraction. A concave lens bulges inward and is thinner in the middle and thicker at the edges. → Refraction is bending of light when it enters obliquely from one transparent medium to another. Light is such an important... Rules to obtain Image from Convex Mirror. A Spherical lens is a piece of transparent glass bound by two spherical surfaces. The change of direction of light because of change of medium is known as Refraction or Refraction of Light. xYz. The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane. Light enters from air to glass having refractive index 1.50. Light is a form of energy that enables us to see things. the film appears brightest at its outer margin, where it is thinnest. Speed of light waves depends on the medium through which they pass as speed of light in air is slightly less than the speed of light in The incident ray, the reflected ray and the normal to the mirror at the point of incidence all lie in the same plane.

The reflecting surface of a spherical mirror may be curved inwards or outwards. For understanding about principle focus and focus length of a spherical mirror first consider the figure given below. Class 10. (like solid, liquid or gas) for their propagation. It is represented by the letter f. There is a relationship between the radius of curvature R, and focal length f, of a spherical mirror and is given by R=2f which means that that the principal focus of a spherical mirror lies midway between the pole and centre of curvature. Whatever be the position of object in front of convex mirror, the image formed by a convex mirror is always behind the mirror, virtual, erect and smaller than the object. This change in speed of … Images formed by Convex Mirror. Light rays basically consist of electromagnetic waves which do not require any material medium Speed of light in vaccum (c) = 3.8 × 10 8 ms −1 Speed of light in glass (v) = ? © 2007-2019 . Distances measured perpendicular to and above the principal axis (along + y-axis) are taken as positive. The refraction of light takes place on going from one medium to another because the speed of light is different in two media.

Your IP: 192.138.189.190 If i is the angle of incidence and r is the angle of refraction then The speed of light in vacuum is 3 × 10 8 m s −1. This point on the principal axis is called the principal focus of the lens. and when this reflected light reaches our eyes we are able to see such non luminous objects. When a light ray is incident normally to the interface of two media then there is no bending of light ray and it goes straight through the medium. Transmitted: - An object is said to transmit light if it allows light to pass through itself and such objects are transparent. Home; Chapter 1-5.
