Practice question · True or false
The angle of incidence equals the angle of refraction when light passes into a denser medium.
Hints
- Reflection or refraction?
- Snell's law, not the mirror law.
Show the answer
False
Why
False. That is the law of reflection. Refraction bends the ray toward the normal on entering a denser medium, following Snell's law , the angles are equal only at normal incidence or when the indices match.
