How it works?

<h2>How Brewster's Angle Calculator Works</h2>

The Brewster's Angle Calculator allows you to determine the specific angle at which light, when incident on a boundary between two media with different refractive indices, is perfectly transmitted with no reflection for the p-polarized component. This angle is known as Brewster's Angle, and it is crucial in applications such as optics, photography, and laser systems where glare and reflection control are essential.

Refractive Index of Medium 1: The refractive index of the medium where the light originates (for instance, air typically has a refractive index of approximately 1.0).
Refractive Index of Medium 2: The refractive index of the second medium, the material the light is entering (e.g., glass has a refractive index around 1.5).

Brewster's Angle is calculated using the following equation:

$$ \theta_B = \arctan\left(\frac{n_2}{n_1}\right) $$

Where:

$ \theta_B $: Brewster's Angle in degrees.
$ n_1 $: Refractive index of the first medium.
$ n_2 $: Refractive index of the second medium.

This calculator uses the provided refractive indices of the two media to instantly compute the Brewster's Angle, enabling quick and accurate measurements for use in various optical applications. By aligning light at Brewster's Angle, you can achieve minimal reflection for the p-polarized light, improving the efficiency of optical systems.
