# 8 Best Free Online Brewster’s Angle Calculator Websites

Here is a list of best free online Brewster’s Angle Calculator websites. Brewster’s Angle or Polarizing Angle is a concept of optics based on the polarization of light when encountered by refractive and reflective surfaces. At Brewster’s angle, the reflected light contains vibrations in only one plane (i.e. polarized). The calculation of Brewster’s angle is important in various fields like designing polarized glasses, designing polarized filters, controlling the reflectivity of surfaces, and more. If you also want to calculate the Brewster’s angle, then check out these online Brewster’s angle calculator websites.

Through these websites, users can quickly calculate Brewster’s angle. To do that, these websites mainly need two parameters: Refractive Index 1 and Refractive Index 2. Refractive Index 1 represents the refractive index of the medium from which the light is coming. On the other hand, Refractive Index 2 represents the refractive index of the medium to which the light is incident. On some websites, users can also specify the SI unit (Radians or Degrees) of Brewster’s angle. An explanation of Brewster’s angle along with the calculation formula is also provided by some calculators. To help new users, I have also provided the calculation steps in the description of each website.

These websites also offer additional online calculators related to various fields like Physics, Finance, Health, Maths, Statistics, and more. Go through the list to learn more about these websites.

Shows Brewster’s angle calculation formula

Brewster's Law is typically expressed as: tan(θB​)=n1​n2​​ Where: θ_B is Brewster's angle (the angle of incidence at which light becomes completely polarized). n1 is the refractive index of the incident medium (the medium from which light is coming). n2 is the refractive index of the transmitting medium (the medium into which light is entering). The formula allows you to calculate Brewster's angle for a given pair of incident and transmitting media with known refractive indices. When light is incident at Brewster's angle, the reflected light will be polarized, with its electric field vector oscillating perpendicular to the plane of incidence.

The Brewster angle, in simple terms, is the angle where its light is polarised.The method of estimating the Brewster angle by this formula:αB = arctan(n2/n1).

Polarized sunglasses, in photography to lessen reflection from the surface, Brewster windows, gas lasers, and solid lasers are examples of Brewster law applications.

Linear polarisation, circular polarisation, and elliptical polarisation are the three forms of polarisation. Linear polarisation occurs when the electric and magnetic fields oscillate in the same direction. In elliptical polarisation, the field directions form an ellipse, whereas in circular polarisation, the field directions rotate at a constant rate.

No, Brewster's angle and the critical angle are not the same, although they are related concepts in optics.
