What else can I help you with?
How do you calculate speed of light in a vacuum?
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
Do relative permittivity and dielectric constant of a medium imply different physical qantities?
Relative permittivity and dielectric constant are often used interchangeably, but they can imply different contexts. Relative permittivity (ε_r) is a dimensionless measure of a material's ability to store electrical energy in an electric field, relative to the vacuum. The term "dielectric constant" traditionally refers to this same quantity, but it can sometimes be used more loosely to describe the material's overall insulating properties. Thus, while they represent similar concepts, the terminology can depend on the specific physical context being discussed.
What is Rydberg constant?
Rydberg constant is 10,973,731.6 m-1. It's found by this sophisticated form, which is: R∞ = mee4/(8ε0²h³c) where: me = rest mass of the electron e = elementary charge ε0 = permittivity of free space h = Planck constant c = speed of light in a vacuum.
How many microns is 30 inches of vacuum?
30in is 762000 microns of vacuum
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
