Activity 1:
We still know how the surrounding object is visible to the eyes. Suppose you are in a room and everything is visible due to the tublight but nothing outside is visible due to the window closing. Now open the window. What will you see? Outside light entering in room by transparent glass and outside objects are visible to us. From this it is clear that if we see clearly through a material is called transparent material. If we take empty glass of water you can see clearly, if we use glass slab it seen clearly. If transparent plastic paper is used you can see objects clearly through a material is called transparent material. If we take empty glass of water you can see clearly, if we use glass slab it seen clearly. If transparent plastic paper is used you can see objects clearly.
Activity 2:
Take colour bottle having liquid inside a bottle. Can you tell that which liquid filled in a bottle? If your answer is no then let’s focusing on a bottle and observe carefully what’s inside the bottle? There is a water inside a bottle. When object does not see clearly through a material is called Translucent material.
Translucent materials are used in a window, in office room, bathroom etc.
Opaque material :
If there is light in room, can you see every object in a room? No, you cannot see everything, because light hits on it reflect back, and that reflected light make us see the object. Behind the object we can’t see what objects are there, because this object does not pass light through it. When a material is something that does not allows light passing through it is called opaque material. In our surrounding there are so many objects which does not allow lights thorough it, like duster, bag, boxes, fridge etc
Q. 1 Why we Cannot see through opaque objects?
Ans : Because object not allow light passing through it.
Q. 2 can we used water as a opaque?
Ans : No, because water is uesd as transparent and it allows light to passing through it.
Q. 3 What is basic difference between transparent and Translucent material?
Ans : In transparent material objects are seen clearly and in Translucent
material objects does not see clearly that is blurb.
