Light is a form of energy that enables us to see objects. There are luminous objects that can produce light and illuminated objects that reflect light falling on them but do not produce their own light. When light falls on or is emitted from an object, our eyes detect that light, making the object visible. Light can be reflected, transmitted, or absorbed when hitting surfaces. Mirrors reflect light following the law of reflection, forming real or virtual images depending on the shape of the reflective surface.

2. What is Light?
Form of energy that enable
us to see the objects

3. Luminous Objects-Objects which can produce
light on their own

4. Illuminated objects- that do not produce
light on their own
but reflect the light that falls upon them

5. Reflection of light
• What makes things visible?
• When light falls upon or is emitted by an object
our eyes detect that light and hence the object
becomes visible to us.
