Reflection of Light; Definitions Luminous objects - generate their own light (the sun) Illuminated objects - reflect light (the moon) Line of Sight - a line from an object or image to your eyes (light from the object travels along this line to your eyes) Slide 2; Line of Sight Both luminous & illuminated objects emit/reflect light in many ...
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 ...
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
Science 8 Chapter 11 11.2: Reflecting Light off Surfaces. Specular Reflection • The reflection of light off a smooth, shiny surface. Laws of Reflection • The incident ray, the reflected ray, and the normal all lie in the same plane. • The angle of incidence equals the angle of reflection. Diffuse Reflection • Occurs when light hits an irregular surface
•When light falls on such a surface, the light rays are reflected at different angles. • In this case, the angle of incidence and the angle of reflection of each ray are not equal. •Hence, the law of reflection is not obeyed in this case and thus the image is not clear. •Such a reflection is called ‘irregular reflection’ or ‘diff
Light and Reflection. Light and Reflection. Light. Characteristics of Light. Not all light is visible to the human eye. What your eyes recognize as “white” light is actually light that can be separated into six elementary colors of the visible spectrum: red, orange, yellow, green, blue, and violet. 544 views • 39 slides
