✔ 最佳答案
sinC = 1/nsinC = 1/1.33
Critical angle, C = sin⁻¹(1/1.33) = 48.8°

Given,
Refractive Index (μ) = 1.33
Critical Angle (c) =?
We know that
sin C = 1/μ
C = sin⁻¹ (1/μ)
= sin⁻¹ (1/1.33)
= 48.75°
≈ 48.8°
∴ Critical Angle (c) = 48.8°
Refractive Index (μ) = 1.33
Critical Angle (c) =?
We know that
sin C = 1/μ
C = sin⁻¹ (1/μ)
= sin⁻¹ (1/1.33)
= 48.75°
≈ 48.8°
∴ Critical Angle (c) = 48.8°
