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 Ncert Solutions Class 10th Physics Chapter Light Key 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. It shows that the image formed by the plane mirror is of the same size as that of the object.
The positive sign shows that the image formed is virtual and erect. Concept Insight - Positive magnification corresponds to virtual and erect image. The numeral value of magnification indicates that the size of the image is that many times the size of the object. According to the mirror formula,. The positive value of magnification indicates that the image formed is virtual.
The positive value of the image height indicates that the image formed is erect. Therefore, the image formed is virtual, erect and smaller in size. Concept Insight - Write the given data in appropriate sign conventions. Then identify the unknown quantities that need to be evaluated. Then put the formulae that are most suitable. The screen should be placed at a distance of 54 cm in front of the given mirror. The negative value of the image height indicates that the image formed is inverted.
Concept Insight - The interpretation of sign convention is the key here. The focal length is negative. Hence, it is a concave lens. Concept Insight - The value of the focal length should be written in metres when substituting in the formula:. Concept Insight: Positive focal length corresponds to convex lens and negative focal length corresponds to concave lens. Enter the OTP sent to your number Change. Resend OTP.

The refractive index of medium 2 with respect to medium 1 is given as, The refractive index of medium 1 with respect to medium 2 is given as,. The relation is given as It can be inferred from the relation that light will travel the slowest in the material which has the highest refractive index and will travel the fastest in the material which has the lowest refractive index.
Concept Insight: While using the formula of power, one should be careful to use the value of focal length expressed in meters only. Case I When the upper half of the lens is covered: In this case, the rays of light coming from the object will be refracted by the lower half of the lens. Case II When the lower half of the lens is covered: In this case, a ray of light coming from the object is refracted by the upper half of the lens.
The negative sign shows that the image is real and formed behind the lens. The position, size, and nature of image are shown in the following ray diagram. Remember: Object distance u is conventionally always taken as negative. A convex lens has a positive focal length. Hence, it is a convex lens or a converging lens. Have an account? Sign In.
