The document is about the phenomenon of refraction, where light changes speed and direction when moving between different mediums like air and water. It discusses how light travels through one medium, air, before entering a glass of water. It then asks questions about arranging the order of mediums light passes through and where the path of light gets deviated when moving from one medium to another.

2. IS IT MAGIC ?

3. ACTIVITY CARD
1. HOW DOES LIGHT TRAVELS?
2. HOW MANY MEDIUM DOES LIGHT
TRAVELS BEFORE ADDING WATER IN TO
THE GLASS?
3. ARRANGE THE MEDIUM IN ORDER
FROM THE COIN TO OUR EYES?
4. HOW MANY MEDIUM DOES LIGHT
TRAVELS,IN SECOND SITUATION?
5. ARRANGE THE MEDIUM IN ORDER
FROM COIN TO OUR EYES?

4. REFRACTION
When light travels from one medium to
another,its path undergoes a deviation.
This phenomenon of light is called
refraction.
