- Properties of Light Answer → Electromagnetic wave, so does not require any medium to travel. → Light tends to travel in straight line. → Light has dual nature i.e. wave as well as particle. → Light casts shadow. → Speed of light is maximum in vaccum. Its value is 3 × 10 ms.
the new theory reconciles the particle properties of light with the wave nature. In this Chapter, we shall study the phenomena of reflection and refraction of light using the straight-line propagation of light.

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 · Light is an electromagnetic wave that can be visible to humans and help humans to see the object. We can also define Light as a form of energy that helps us to see. Light Wave contains a minute packet of energy particles called photons.
