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 board exams. Light Reflection and Refraction Class 10 Notes aims at easing out your learning and revision process. Reflection is one of the unique properties of light. It is the reflection of light, which enables us to see any object. Reflection: The bouncing back of rays of light from a polished and shiny surface is called reflection or reflection of light.

Students preparing for their board examination can go through Class 10 science light reflection and refraction notes to review important concepts quickly.
It will also enable them to gain a comprehensive understanding of the same. Class 10 Science Chapter 10 notes start with an overview of the following essential topics from the text:. This section from notes of ch light Class 10 begins with discussing important concepts like light, rectilinear propagation of light, the reflection of light etc. The two types of reflection of light — regular reflection or specular reflection and irregular or diffused reflection are also explained with the help of diagrams.
The main laws of reflection which include the following:. The angle of reflection and angle of incidence are equal. At the point of incidence, the incident ray, normal and the reflected ray lie in the same plane.
These laws have also been discussed in a simple language to facilitate better understanding on the part of students. Light reflection and refraction Class 10 notes also provide step-by-step guidance on how to draw the reflection of light by a plane surface. Students will also be able to review their understanding of the nature of an image that is formed by a plane reflecting surface. Accordingly, an image can be classified into two types - virtual and real.
Lastly, notes of Chapter 10 science Class 10 also provide pointers that students must keep in mind while constructing ray diagrams. In the next part, from light reflection and refraction Class 10 notes, students can revise spherical mirrors, which are essential objects with a hollow sphere of glass or plastic that has a polished and reflecting surface.
Based on the surface of mirrors, it can be classified into two types — convex and concave. He main differences between the two have been explained thoroughly so that students can memorise the essential points quickly. Apart from that, several important terms have also been discussed in light reflection and refraction Class 10 notes.
These are as follows:. Centre of curvature. Radius of Curvature. Linear Aperture. Principal axis. Secondary Axis. Principal focus. Focal length. Additionally, students will also be able to revise sign conventions that are used to measure distances in a spherical mirror ray diagram from notes of Chapter 10 Class 10 science. These include essential points, such as:. An object should always be placed to the left side of a reflecting surface. When a distance measured from the direction of the incident ray, it will always be positive.
When it is measured in the opposite direction, it will be negative. Some of the main uses of concave and convex mirrors have also been mentioned here.
For instance, convex mirrors are used as rear-view mirrors, reflectors in street lamps, vigilance mirrors in departmental stores and the like. On the other hand, concave mirrors as automobile reflectors, shaving mirrors etc.
Magnification, which is one of the crucial topics in this Chapter, has also been explained thoroughly in light reflection and refraction Class 10 notes so that you can have a thorough grasp on the same. In this segment, students will revise important aspects of refraction, which is a phenomenon where light passes deviate from one medium to another. Some essential terms related to refraction has also been explained straightforwardly in light reflection and refraction Class 10 notes to aid students with their revision before exams.
These include the following:. Angle of refraction. Angle of incidence. Incident ray. Point of incidence. Refracted ray. Laws of refraction. This section from light reflection and refraction Class 10 notes also explains the process of refraction of light through glass slab, which will enable students to retain the fundamental concepts.
Apart from that, students can also refer to Vedantu revision notes to gain more clarity on the lens, types of lens and their uses and concept of magnification.
Besides the light reflection and refraction class 10 notes, students can also access the online courses on the subject held by experienced teachers for thorough preparation.

CBSE Science notes. Economics Notes for class 11th statistics. Economics Notes for class 11th Development. Economics Notes for class 12th Vyashti. Economics Notes for class 12th Samashti. Light-Reflection and Refraction. An object reflects light that falls on it.
Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection. Reflected light: Light which goes back after reflection is called reflected light. Spherical Mirror: If the reflecting surface is part of the hollow sphere then the mirror is a spherical mirror. The spherical mirror is of two types:. Linear Magnification: This is the ratio of the height of the image to the height of the object.
A group of rays of light emitted by a source of light is called a beam of light. A light beam is of three types. Reflection of Light : There are some surfaces which have ability to send the light back in the same medium when light strikes it. Image : When light rays meet or appear to meet after reflection from a mirror,then it is called an image. Real Image : It is a kind of image which is formed by actual intersection of light rays after reflection. Virtual Image : It is a kind of image which is formed by producing the reflected rays backward after reflection.

Соши прочитала снова: - …Искусственно произведенный, обогащенный нейтронами изотоп урана с атомным весом 238. - Двести тридцать восемь? - воскликнула Сьюзан. - Разве мы не знаем, что в хиросимской бомбе был другой изотоп урана. Все вокруг недоуменно переглянулись.
Здесь около сотни пунктов. Мы не можем вычесть их все одно из другого.

У шифров-убийц обычно есть функция злопамятства - чтобы не допустить использования метода проб и ошибок. Некорректный ввод только ускорит процесс разрушения. Два некорректных ввода - и шифр навсегда захлопнется от нас на замок. Тогда всему придет конец. Директор нахмурился и повернулся к экрану. - Мистер Беккер, я был не прав.
Когда он шел к выходу по главному коридору, путь ему преградил охранник с телефонной трубкой в руке. - Мистер Беккер, подождите минутку. - В чем дело? - Беккер не рассчитывал, что все это займет так много времени, и теперь опаздывал на свой обычный субботний теннисный матч.
