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 !!

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

Relative motion in 3D (three dimension)

I wanted to ask that is there relative velocity in three dimennsion? if yes then explain it. (Apoorv Katoch asks)

Answer: As we know, motion is relative. Relative velocity can be defined in three dimension also.

Relative velocity is defined as the velocity of one body when the other is assumed to be at rest.

Relative velocity is defined as VBA=VBVwhere VBA is relative velocity of B relative to A

It is true in 1D, 2D or 3D

Principle of Homogenity of Dimensions

Binay Sharma asked:

“Explain the applications of the Principle of homogenity of Dimensions and its importance”

Principle of homogenity of dimensions states that “For an equation to be dimansionally correct, the dimensions of each term on LHS must be equal to the dimensions of each term on RHS.”

Applications

1. To determine the dimensions of an unknown quantity in an equation

2. To check the accuracy of an equation

3. To derive a formula connecting the given (or assumed) physical quantities

4. To convert a physical quantity from one system of unit to other
