So, 10th Science chapter 10 question answers are useful for UP Board students. Properties of images formed by a plane mirrors: i The image formed by a plane mirror is virtual and erect. Properties of the image formed by a convex mirror: i This image is always virtual and erect. Laws of refraction of light: The refraction of light obeys the following two laws: First law: The incident ray, the refracted ray and normal to the surface of separation at the point of incidence, all lie in the same plane.
Second law: The ratio of the sine of the angle of incidence and the sine of the angle of refraction is constant for a given pair of media.
The ratio n2 is called refractive index of the second medium with respect to the first medium. Refraction of light: The phenomenon of bending of light from its straight line path as it passes obliquely from one transparent medium to another is called refraction of light. The path of the ray of light in the first medium is called incident ray. The path of the ray of light in the second medium is called refracted ray.
The angle between the incident ray and the normal at the surface of separation is called angle of incidence i. The angle between the refracted ray and the normal at the surface of separation is called angle of refraction ncert solutions class 10th light wr. Question 1: Give three points of difference between real and virtual images. Answer 1: Real Image: i Here the rays actually meet at the image point. Question 2: Distinguish between a concave and convex lens.
Answer 2: Convex lens a It is thicker at the centre than at the edges. Concave lens: a It is thinner at the centre than at the edges. Question 1: Define the principal focus of a concave mirror. Calculate the focal length of the mirror of radius of curvature of 20 cm. Answer 1: The principal focus of concave mirror is a point on its principal axis at which a beam of light parallel to the principal axis actually converges after reflection from the ncert solutions class 10th light wr. Question 2: State the type of mirror preferred as i rear view mirror in vehicles, ii shaving mirror.
Justify your answer giving two reason in each case. Answer 2: i A convex mirror is preferred as a rear-view mirror because a It always forms an erect, virtual and diminished image of an object placed anywhere in front of it. This suggests that the speed of light in diamond will reduce by a factor 2.
The S. It is denoted by D. Important questions and CBSE previous years board questions related to chapter ncert solutions class 10th light wr are given with answers. List four properties of the image formed by a plane mirror.
List the four properties of the image formed by a convex mirror. State the laws of refraction of light. What is meant by refraction of light? Important Questions on 10th Science Chapter 10 Define the principal focus of a concave mirror. Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror.
This point is known as the principal focus of the concave mirror. The radius of curvature of a spherical mirror is 20 cm. What is its focal length? Name the mirror that can give an erect and enlarged image of an object. When an object is placed between the pole and the principal focus of a concave mirror, the image formed is virtual, erect, and enlarged.
Why do we prefer ncert solutions class 10th light wr convex mirror ncert solutions class 10th light wr a rear-view mirror in vehicles? Convex mirrors give a virtual, erect, and diminished image of the objects placed in front of. They are preferred as a rear-view mirror in vehicles because they give a wider field of view, which allows the driver to see most of the traffic behind.
A ray of light travelling in air enters obliquely into water. Does the light ray bend towards the normal or away from the normal? The light ray bends towards the normal.
When a ray of light travels from an optically rarer medium to an optically denser medium, it gets bent towards the normal. Since water is optically denser than air, a ray of light travelling from air into the water will bend towards the normal.
The refractive index of diamond ncert solutions class 10th light wr 2. What is the meaning ncert solutions class 10th light wr this statement?
Define 1 dioptre of power of a lens. Power of lens is defined as the reciprocal of its focal length. Chapter Human Eye and Colourful World �.

NCERT is also known as the publishing body or publisher. It is an autonomous organisation set up in by the Government of India, aiming to assist and advise the Central as well as the State Governments on policies and programmes for qualitative improvement in school education. The function of NCERT is to conduct and support educational research and to offer training in educational research methodology.
Chapter 8 - How do Organisms Reproduce? Chapter 9 - Heredity and Evolution. Chapter 10 - Light Reflection and Refraction. Chapter 11 - Human Eye and Colourful World. Chapter 12 - Electricity. Chapter 13 - Magnetic Effects of Electric Current.
Chapter 14 - Sources of Energy. Chapter 15 - Our Environment. Chapter 16 - Management of Natural Resources. It is quite necessary to have at least basic knowledge of Science which may help you in the future. Class 10 Science Chapter 10 NCERT Solutions are structured in a comprehensive and presentable way to provide students with complete coverage of the topics and scientific terms which can help students in scoring well in their exams as well as gain perspective towards career goals.
Chapter 10 Class 10 Science is mostly about reflection and refraction of light. The main topics included consist of spherical mirrors, magnification, reflection, refraction and power of a lens. To provide simplification, Light Reflection and Refraction Class 10 Solutions include various diagrams, logical problems and detailed content in simple words.
The topic Reflection of Light Class 10 refers to light waves bouncing off the surface Ncert Solutions Class 10th Light Chapter Review of objects that do not have the capability of absorbing energy produced by radiation.
A surface of a pool, for example, will display clarity of surrounding objects when still. Whereas, all the rays would be scattered once a rock is thrown inside it preventing systematic reflection of light. Refraction of light Class 10, on the other hand, refers to the bending of light waves when it travels from a faster to a slower medium. Images formed by lenses and our eyes exist due to this process.
All the aforementioned topics are thoroughly explained under Chapter 10 Science Class 10 solutions by teachers having expertise in the subject.
