What is the critical angle for a ray of light travelling from glass (refractive index = 1.5) to air?
A. sin^-1(1/1.5)✓ Correct Answer
B. sin^-1(1.5)
C. cos^-1(1/1.5)
D. tan^-1(1.5)
💡 Solution & Explanation
The critical angle C for light traveling from a denser medium of refractive index n to a rarer medium like air is determined by the mathematical relation sin C = 1/n. Substituting the given refractive index value of 1.5 yields sin C = 1/1.5, meaning C equals the inverse sine of that ratio.
