Question 24
Refraction of LightIf the refractive index of a medium is √2, what is the critical angle?
- A.45°
- B.50°12'
- C.56°25'
- D.75°
- E.90°.
Show the answer and explanation
Answer: A (45°)
Explanation
sin C = 1/n = 1/√2, so C = 45°.
If the refractive index of a medium is √2, what is the critical angle?
Answer: A (45°)
sin C = 1/n = 1/√2, so C = 45°.
