Explanation:

Light is a form of energy that enables us to see things around us. The source of light is called a luminous object.

Types of Objects:

There are two types of objects based on their ability to produce light:

1. Luminous Object: A luminous object is an object that produces light on its own. For example, the Sun, a light bulb, a candle, and a firefly are all luminous objects.

2. Non-Luminous Object: A non-luminous object is an object that does not produce light on its own. It can only reflect light produced by a luminous object. For example, a book, a table, and a pencil are all non-luminous objects.

Properties of Light:

Light has the following properties:

1. Reflection: Light can bounce back when it hits a surface. This property is called reflection. The angle of incidence is equal to the angle of reflection.

2. Refraction: Light can bend when it passes through a medium of different densities. This property is called refraction.

3. Absorption: Light can be absorbed by objects. When light is absorbed, it is converted into heat energy.

Uses of Light:

Light has many uses in our daily lives. Some of the uses of light are:

1. Illumination: Light is used to light up our homes and streets.

2. Photography: Light is used to take photographs.

3. Communication: Light is used in fiber optic cables to transmit information.

4. Medical Science: Light is used in medical science for diagnosis and treatment.

Conclusion:

In conclusion, light is a form of energy that enables us to see things around us. The source of light is called a luminous object. There are many uses of light in our daily lives, and it has many properties that make it unique.
