nature. We shall try to understand in this Chapter the reflection of light by spherical mirrors and refraction of light and their application in real life situations. 10.1 REFLECTION OF LIGHT A highly polished surface, such as a mirror, reflects most of the light falling on it. You are already familiar with the laws of reflection of light.
Jan 22, 2024 · CBSE Class 10 Science Notes Chapter 10 Light Reflection and Refraction. REFLECTION. Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection. Incident light: Light which falls on the surface is called incident light. Reflected light: Light which goes back after reflection is ...

Page Number: 168 Question 1 Define the principal focus of a concave mirror. Answer: The principal focus of a concave mirror is a point on its principal axis to which all the light rays which are parallel and close to the axis, converge after reflection from the concave mirror. Question 2 The radius of curvature of a spherical mirror is 20 cm. What ...

- Introduction to Light – Reflection & Refraction. In Class 10 Science Chapter 10 Light, the phenomena of reflection and refraction of light using the straight-line propagation of light are taught to students.
- Chapter Summary Video. Light: Definition. Light is a form of energy that enables us to see things. Light starts from a source and bounces off objects which are perceived by our eyes, and our brain processes this signal, which eventually enables us to see.
- Laws of Reflection. Light Incident on the Surface Separating Two Media. When light travels from one medium to another medium it either: gets absorbed (absorption)
- Spherical Mirrors. Spherical Mirror. Consider a hollow sphere with a very smooth and polished inside surface and an outer surface with a coating of mercury so that no light can come out.
Dec 12, 2023 · Class 10 Physics Chapter 10 Light-Reflection and Refraction is one of the most important chapters to learn. In this article, we will learn about reflection, types of reflection, refraction, images formed by spherical, spherical lenses, and different types of lenses and mirrors, magnification, Power of lens, and light passing through a prism.

May 10, 2021 · The speed of light in vacuum is 3 x 108 ms-1. Answer. Refractive index of a medium, n m = Speed of light in vacuum/Speed of light in the medium. Speed of light in vacuum, c = 3 × 10 8 ms -1. Refractive index of glass, n g = 1.50. Speed of light in the glass, v = Speed of light in vacuum/ Refractive index of glass. = c/n g.
