REFLECTION OF LIGHT
9. REFLECTION OF LIGHT points to remember : 1. Transmission of light : Light coming out from a source spreads in all directions. Light is transmitted in a straight line. 2. Reflection of light : The turning back of the rays of light after falling on a surface is called the reflection of light. 3. Image formed in a plane mirror : The image formed in a plane mirror is upright, laterally inverted, of the same size as the object and as far behind the mirror as the object is in front of the mirror. 4. Laws of reflection of light : (1) The incident ray, the reflected ray and the normal to the reflecting surface at the point of incidence are in the same plane. (2) The incident ray and the reflected ray are on the opposite sides of the normal. (3) The angle of incidence and the angle of reflection are of equal measure. 5. Types of reflection of light : Regular reflection and irregular reflection are the two types of reflection. If the reflecting surface ...
