What Causes a spoon in a glass of water to appear distorted ???
When light ray travels from one medium(air) to another medium of different density(water/glass), the light ray changes its direction and bend. This bending of light is Refraction.
When white light passes through a prism,it will split into different colours.
Why??
Because different colours have different angles of refraction..
then a spectrum of colours is produced which is made up of 7 colours which makes up the rainbow.
Red,Orange,Yellow,Green,Blue,Indigo,Violet.
