Critical Angle

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Critical Angle is an essential tool for understanding Critical Angle in quantitative terms. Calculate θc = arcsin(n2/n1).

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = (Math.asin(n2÷n1) × 180) ÷ π
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
n1 n1 (High Index)
n2 n2 (Low Index)

Practical Calculation Example

Problem

Calculating the result when:

  • n1 (High Index) = 1.5
  • n2 (Low Index) = 1.5

Solution

Substituting into Eq 1.1:

Result = (Math.asin(1.5÷1.5) × 180) ÷ π
