Prism
Minimum Angle of Deviation
12
⚡ Quick Summary
The minimum angle of deviation occurs when a ray passes symmetrically through a prism.
μ = sin((A + δm)/2) / sin(A/2)
The refractive index (μ) of the prism is related to the angle of the prism (A) and the minimum angle of deviation (δm) by the formula: μ = sin((A + δm)/2) / sin(A/2). For an equilateral prism, A = 60°.
