Jabarkan Properties dari Rohangan hapa dalam bahasa sunda

Many properties of space approach non-zero values in a vacuum that approaches perfection. These idéal physical constants are often called free space constants. Some of the common ones are as follows:

The speed of light approaches 299,792,458 m/s, but is always slower

Index of refraction approaches 1.0, but is always higher

Electric permittivity () approaches 8.8541878176x10−12 farads per meter (F/m).

Magnetic permeability (μ0) approaches 4π×10−7 N/A2.

Characteristic impedance () approaches 376.73 Ω.
