Reflection. Light gets reflected off surfaces. Any surface that is really well-polished or shiny acts as a mirror. The phenomenon of light bouncing off surfaces is called reflection. Laws of reflection. The ray of light that strikes a reflecting surface is called the incident ray, and the ray that gets reflected back is called the reflected ray.
These NCERT Solutions present you with answers to the questions on the meaning of reflection, laws of reflection, types of mirrors, kaleidoscope and its construction, the concept of the rainbow and 7 colours, dispersion of light, parts of the human eye and defects of the human eye.
Jul 3, 2023 · Reflection of Light. The process of sending back light rays which fall on the surface of an object, is called reflection of light. A plane mirror reflects almost all the light which falls on it. In order to study the reflection of light, we need an apparatus which can produce a thin beam of light.
Jun 9, 2019 · Reflection of Light occurs when a ray of light approaches a smooth surface and bounces back. The laws of reflection determine the reflection of incident light rays on reflecting surfaces. Know more at BYJU'S.
Oct 4, 2019 · Answer: The laws of reflections are: The incident ray, the normal and the reflected ray, all lie in the same plane. The angle of incidence is equal to the angle of reflection. Question 5.
between the normal and incident ray is called the angle of incidence (∠∠∠i). The angle between the normal and the reflected ray is known as the angle of reflection (∠∠∠r) (Fig. 16.3). Measure the angle of incidence and the angle of reflection. Repeat the activity several times by changing the angle of incidence.
A mirror is a glass having a shiny surface. When light falls on a mirror it is reflected back. Hence a mirror changes the direction of light that falls upon it. Figure 2 Light falling on a mirror. The laws of reflection. What is the reflection of light? Figure 3 Reflection of Light.
