REFLECTION OF LIGHT PowerPoint Presentation with Activities - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. The document discusses reflection of light including defining reflection, identifying the laws of reflection, and interpreting diagrams of reflection. It includes activities like watching a video on ...
4 Reflection The law of reflection states that the angle of reflection is equal to the angle of incidence. A ray that hits the surface is the incident ray. The ray that bounces off the surface is the reflected ray. *An incidence is the intersection of a line, or something moving in a straight line, such as a beam of light, with a surface.
1) Light :- i) Light is a form of energy which helps us to see objects. ii) When light falls on objects, it reflects the light and when the reflected light reaches our eyes then we see the objects. iii) Light travels in straight line. iv) The common phenomena of light are formation of shadows, formation of images by mirrors and lenses, bending of light by a medium, twinkling of stars ...
Diffuse reflection (irregular reflection), the irregular surface can be considered to be made up of a large number of small planar reflecting surfaces positioned at slightly different angles. 5 Refraction The bending or change in direction of light is known as Refraction.
LIGHT : REFLECTION AND REFRACTION. LIGHT • Light is a form of electromagnetic radiation that causes the sensation of sight. • It is an indispensable tool without which we cannot explore the colorful beauty of nature. • The blue sky, the rainbow, the red of the sunrise and sunset, the twinkling of stars, the radiance of sparkling diamonds and pearls, and shining color of gems are just ...
When light falls on a highly polished surface like a mirror most of . the light is sent back into the same medium. This process is called . reflection of light. a) Laws of reflection of light:-i) The angle of incidence is equal to the angle of reflection. ii) The incident ray, the reflected ray and the normal to the mirror at

An image is formed when the light rays coming from an object meet at a point after reflection from a mirror (or refraction from lens). The images are of two types. Real Images:- Real images are formed when rays of light that comes from an object (or source) meets at a point after reflection from a mirror (or refraction from a lens).
4 + The incident ray (the light ray that strikes the mirror) will reflect off the mirror at the same angle from the normal as it struck the mirror. The normal is an imaginary line that runs perpendicular to the reflective surface. When light rays bounce off of a mirrored surface, an image is created – a reproduction of the original object.
This lesson covers the basics of reflected light, honing in on exam points including the normal and the angles of incidence and reflection. The experiment for reflection of light and a ray box is included, as well as description of specular and diffuse reflections and how to draw diagrams with multiple reflections from surfaces.
