Luminous and Non Luminous Objects- Science Class 6


In this blog, you will learn about Luminous and Non Luminous Objects, their defintion and examples.


During the daytime, we see so many wonderful and colorful things around us. We see blue sky, flowers of different colors, green plants and trees, clouds of white color. We enjoy seeing the scenes of sunrise and sunset. On the way to the market, we see cars, buses, and people in colorful dresses. After the sunset, all these scenes change.


Everything around us appears dark. In a completely dark room, we cannot see any object present in the room. When we switch on an electric bulb or light a candle, the objects present in the room become visible. Without light things cannot be seen Light helps us see objects. During the daytime, sunlight enables us to see the things around us. The sun emits light of its own.


What is a Luminous Object?


An object that emits or gives out the light of its own is called a luminous object. Other examples of luminous objects are:- a glowing bulb, a lighted candle, stars, and a bonfire.


Non-Luminous Objects:- Objects that don�t give out light of their own are called non�luminous objects. Most of the objects around us are non-luminous.


We see objects around us when light from the sun or any other luminous object falls on them and then it reaches our eyes.


Examples of non-luminous objects are; the moon, a tree, a book, a pen, a chair, and a table.

Non Luminous Objects List: Planets, coal, a piece of cloth, moon, furniture, bushes, electric poles, metals, houses, stones.


Luminous and Non Luminous Objects


Let's learn about transparent, translucent and opaque objects and their examples.


Transparent Objects
There are so many objects around us through which things can be seen, like pure water, window glass, etc. Those substances or materials, through which things can be seen, are called transparent
Transparent materials allow light to pass through them.


Other examples of transparent materials are cellophane, ice, air, polythene sheet, acrylic sheet, and diamond.


Translucent Objects
Objects, that allow some light to pass through them, are called translucent objects. We can see through them but not clearly.


Examples of translucent objects are; tissue paper, waxed paper, butter paper, frosted glass, and sunglasses.


Opaque Objects
There are so many objects around us, through which we are not able to see things. These objects are called opaque. Opaque objects or materials do not allow any light to pass through them. Most of the objects in our surroundings are opaque objects.


Examples of opaque objects are metal sheets, wood, buildings, trees, Bakelite, a ceramic plate, a book, a pencil box, and a leather sheet.
