Critical Angle for Light
Find critical angle when light dey leave optical material wey get higher refractive index.
Your numbers
Critical angle measured from the normal
Ideal SI-unit model for learning. Real components, tolerances, losses and safe operating limits need separate checking.

Formula
Use θ = asin(n₂/n₁). n₁ na incident refractive index and n₂ na transmitted refractive index, with n₁ > n₂. Measure di critical angle from di normal; result dey show degrees.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
