Question: A ray of light travels from air into a glass block. The angle of incidence (i) and angle of refraction (r) are recorded. Calculate the refractive index.

Data Table (Example):

| Angle of incidence, i (°) | Angle of refraction, r (°) | sin i | sin r | n = sin i / sin r | |---------------------------|----------------------------|-------|-------|-------------------| | 20 | 13 | 0.342 | 0.225 | 1.52 | | 30 | 19 | 0.500 | 0.326 | 1.53 | | 40 | 25 | 0.643 | 0.423 | 1.52 | | 50 | 31 | 0.766 | 0.515 | 1.49 | Question: A ray of light travels from air

Conclusion (Jawapan):
The average refractive index of glass, n = (1.52 + 1.53 + 1.52 + 1.49) / 4 = 1.515
Thus, the refractive index of the glass block is 1.52.
