measure various distances: The object is always positioned to the left of the mirror. All distances are measured from the mirror's pole. Distances measured in the direction of the incident ray are positive, while distances measured in the opposite direction are negative.
- Introduction-Reflection. → Light is the form of energy that provides sensation of vision. → Some common phenomena associated with lights are image formation by mirrors, the twinkling of stars, the beautiful colours of a rainbow, bending of light by a medium and so on.
- Properties of Light. → Electromagnetic wave, so does not require any medium to travel. → Light tends to travel in straight line. → Light has dual nature i.e.
- Reflection. → Bouncing back of light when it strikes on a polished surface like mirror. Laws of Reflection. (i) Angle of incidence is equal to the angle of reflection.
- Image Formed by Plane Mirror. Characteristics of Image formed by Plane Mirror. (i) Virtual and erect. (ii) Size of image is equal to the size of object.
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.
CBSE Class 10 Science Chapter 10 Light Reflection and Refraction Notes. Visible light or light is an electromagnetic radiation found on the electromagnetic spectrum which enables us to see light. Objects reflect some colours of the spectrum when light falls on them. Learn in detail about light and discover other interesting concepts by ...

Apr 10, 2024 · In most cases, an object’s height is measured as positive when it is above the principal axis, while an image’s height is measured as negative when it is below the principal axis. Refraction Through a Glass Slab and Refractive Index
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.
