- Properties of light Light travels in a straight line Light travels at very fast speed. Light does not require any medium to travel. When light strikes a surface, it bounces back, it is called reflection of light. Light can pass through some material by bending through it. This is called refraction of light Light is composed of many colors

Jan 27, 2024 · Light is a form of energy which enables us to see objects from where it comes or reflected. We can detect light with our eyes. Light Travelling along a Straight Line.
Nov 27, 2023 · This comprehensive guide covers Chapter 15 (now chapter 11)– Light, designed for Class 7 Science. It explores the nature of light, its travel, reflection, refraction, and dispersion, along with practical applications of spherical mirrors and lenses. The notes are tailored to simplify complex concepts, making them accessible for young learners ...
- Light always travels in straight line. For instance, if you look at the flame of a candle with a straight pipe we can easily view the candle. However, if we bend the pipe we cannot view the candle and the light coming through it because it is blocked.
- Reflection of light by plane mirror. What is an image?
- Image of Candle Formed by a Mirror. As a mirror reflects light, an image of the object that is in front of the mirror is formed on it. The image of an object can be defined as the impression of the object created by the light on the mirror.
- Inverted Image of a Candle. Left-right inversion of the image.
White light is made up of seven different colours. Properties of Light: A. Rectilinear Propagation of Light: The quality of light that allows it to move in a straight line in any direction. The direction in which light travels to form a ray. B. Light Reflection: This is the phenomenon of light rebounding back after striking an object's surface.

The path of light gets blocked when an object covers the source of light. This is illustrated by trying to see the flame of a candle using a straight pipe and then with a bent pipe. This proves tha...
When light is incident on a certain surface, it either gets reflected or bounces back. Such surfaces are really well polished and act like a mirror. The phenomenon of light bouncing off surfaces is called reflection. To know more about Reflection of Light, visit here.
The ray of light that strikes a reflecting surface is called as the incident ray and the ray that gets reflected back is called the reflected rayThe imaginary line that is perpendicular to the reflecting surface at the point of incidence is called the normalAngle of incidence ∠i is the angle between the incident ray and the normal. Angle of reflection ∠r is the angle between the reflected ray and the normal.Law of Reflection states that the angle of incidence ∠i is always equal to the Angle of reflection ∠r (∠i=∠r). The angle of incidence, angle of reflection and the normal all lie on the same planeLight is the form of energy that makes things visible to us. Switch on the torch in a dark room. The beam of light will be absolutely straight. This shows that light travels in a straight line. Propagation of light in a straight line is known as rectangle propagation of light.
