Question

What two constants is the speed of light in vacuum defined from?

Answer 1

The speed of light can be calculated with two constants that are

_o value and

_o value

here _o is permiability the value of _o is = 4 x 10^-7 H/m.

The permiability of a vacuum is a physical constant equivalent to 4 x 10^-7 H/m.

It is denoted with _o.

permiability as a rule is symbolized _o, and is a consistent of proportionality that

exists between attractive transition thickness

and attractive field quality in a given medium.

The permittivity ofa vacuum is a physical constant and is equal to 8.85 x 10^-12 F/m.

It is symbolized _o.

When all is said in done, permittivity is symbolized and is a steady of proportionality that

exists between electric dislodging and electric field force in a given medium.

so using equation of

maxwell equation C = 1/(_oo)^1/2

= 1/( 4 x 3.14 x 10^-7 x 8.85 x 10^-12 )^1/2

C = 3 x 10⁸ m/s in a vaccum approximately
