   It is only when light from an object enters our eyes that we see the object. The light may have been emitted by the object, or may have been reflected by it. You learnt in Class VII that a polished or a shiny surface can act as a mirror. A mirror changes the direction of light that falls on it.

   What is light in NCERT class 7 Science notes Chapter 15?

   • Here we have given NCERT Class 7 Science Notes Chapter 15 Light. In this world, we usually see a variety of objects. Sometimes, we are unable to see anything in a dark room but on lighting up the room, we are able to see the things in the room. Since, it is an obvious question arising that what makes thing visible. So, its answer is light.

   Why do we study the properties of light?

   • A study of the properties of light helps us to explore them. By observing the common optical phenomena around us, we may conclude that light seems to travel in straight lines. The fact that a small source of light casts a sharp shadow of an opaque object points to this straight-line path of light, usually indicated as a ray of light.

   What is a reflection of light?

   • Reflection of Light There are some certain situations in which a mirror or shiny surfaces like stainless steel plate, shining steel spoon act as a mirror, can change the direction of light that falls on it. So, this process of change in direction of light by a mirror is called a reflection of light.

   What do you learn about lenses in class VII?

   • Recall what you learnt about lenses in Class VII. The lens focuses light on the back of the eye, on a layer called retina (Fig. 16.14). The retina contains several nerve cells. Sensations felt by the nerve cells are then transmitted to the brain through the optic nerve. There are two kinds of cells– (ii) rods, which are sensitive to dim light.

   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.
