Question

How to find densional formula of speed of light?

Answer 1

speed of light

means speed

speed is distance tarvelled / time

so LT^-1 is the anwer

Answer 2

$\large{\underline{\boxed{ Answer}}}$

The dimensional formula of speed of light is same as the dimension of speed.

And, we know the dimensional formula of speed is given by :-

$\boxed{\sf{ V = \frac{S}{t} }}$

Dimensional formula of S = L

dimensional formula of T = T

therefore,dimensional formula of speed of light =

$= > v = \frac{l}{t}$

$= > v = l {t}^{ - 1}$

hence, dimensional formula for speed of light is $l {t}^{ - 1}$
