Yes, if you mean [tex]\epsilon=\epsilon_r\epsilon_0.[/tex]neu said:ok so: [tex] \frac{1}{c}=\sqrt{\epsilon_{0}\mu_{0}}[/tex]
so how is [tex]\epsilon[/tex] and [tex]\mu[/tex] related to c?
is it [tex]\frac{n}{c}=\sqrt{\epsilon\mu}[/tex]?
Permitivity is a physical property that describes the ability of a material to store an electric charge. It is typically represented by the Greek letter epsilon (ε) and is measured in units of farads per meter (F/m).
Permitivity is directly related to electric fields. In the presence of an electric field, a material with a high permitivity will experience a greater displacement of electrons, resulting in a higher electric polarization and a stronger interaction with the electric field.
Relative permitivity, also known as dielectric constant, is a dimensionless quantity that compares the permitivity of a material to the permitivity of a vacuum. It is often denoted by the symbol εr and is used to describe how strongly a material can be polarized in an electric field compared to a vacuum.
Relative permitivity is typically measured by comparing the capacitance of a capacitor filled with the material in question to the capacitance of an empty capacitor. The ratio of the two capacitances is equal to the relative permitivity of the material.
Permitivity and relative permitivity have many practical applications in various fields such as electronics, telecommunications, and materials science. They are used to design and optimize electronic components, insulators, and capacitors, as well as to study the properties of materials and their interactions with electric fields.
