When light travels from denser to less dense medium: angle of incidence where refracted ray emerges at 90° to normal
n=1sinCn = \frac{1}{\sin C}n=sinC1
When angle of incidence exceeds the critical angle
Light travels from denser (glass) to less dense (air) medium
Bends away from the normal
Flat-side down on white paper
Start with a small angle of incidence, then gradually increase it
Refracted ray emerges parallel to glass surface (90° to normal)
Repeat experiment 3-4 times
Read protractor from directly above, perpendicular to scale
Higher refractive index means smaller critical angle
Ray box
Mark the path of the incident ray that enters the glass block
Keep glass block fixed after marking outline and centre
