Relative permittivity, also known as the dielectric constant, is a measure of a material's ability to store electrical energy in an electric field relative to the vacuum. It is a dimensionless quantity that indicates how much a material can reduce the electric field compared to a vacuum, affecting capacitance and the propagation of electromagnetic waves in the material.

A vacuum is a space devoid of matter, where the pressure is significantly lower than atmospheric pressure, often achieved artificially in laboratory settings. It plays a crucial role in various scientific and industrial applications, including physics experiments, electronics manufacturing, and space exploration.

A dimensionless quantity is a pure number without any physical units, often arising from the ratio of two quantities with the same dimensions, allowing for comparison across different systems. These quantities are crucial in scientific fields as they provide scale-invariant insights, facilitating the understanding of physical phenomena and the derivation of universal laws.
