the 4th dimension has always been predicted as a penalty of the reflection of light but when i searched it for long – more description has not been found ……… how can it be possible to hav a dimension which is caused to exist due to a physical matter – LIGHT !!!

The fourth dimension is time

X Y Z co ordinates are the three other

5:54pm

wow from my knowledge – its not so

5:54pm

?

5:54pm

it is said dat the fourth dimension is caused due to the penalty of reflection of light !!

for eg :

if we take a crystal cude

&

see its reflection

its not uniform

(ts our observation )

now joining the

ends of these cubes (reflection & original

give rise to the forth dimension

yup . there r diff reference

& we can only predict caz we r trapped in the 3 -d world & we cant experience dimensions superior to ud !!

5:57pm

SO, thinking like that there is no problem in arguing on multidimensions

5 or 6 or even more

If you say you have to create a theory which supports

The proposal for existence of a fourth dimension was made by mathematicians

And time was the physical quantity first accepted as the fourth dimension

5:59pm

ya who knows – it could even happen but before tat i need to study & understand a lot of concepts & i should start taking things with more observation

& need more investment ……

5:59pm

ok

The idea you were talking was developed by Mobius

## A Falling drop! Watch the picture and explain it

You can see below the photograph of a drop of water falling on water surface. Can anyone explain the observation?

## Particle theory of light and refraction

According to particle theory of light if a light ray bends toward the normal while entering from medium 1 to medium 2 then how the velocity of light in medium 2 is greater than the velocity of light in medium 1 ?

When a medium enters a denser medium from a rarer medium, it bends towards the normal. This is the observation we have in hand and this phenomenon is called refraction.

Sir Isaac Newton tried to explain the phenomenon of refraction using his particle theory. He said that the particles of the denser medium attracts the particles with stronger force towards it which makes it bend towards the normal.

If there is such a force of attraction, then the speed of light would increase inside a denser medium. When the velocity of light in different media was determined by Foucault and other scientists, it was found that the velocity of light in denser medium is less than that in a rarer medium. So, Newton’s explanation of refraction was proved wrong.
