Table 1:
- deviation angles and laser heights.

The refractive index values were calculated using the minimum deviation formula with errors in deviation angles of ±0.5° and the angle of the prism (59.0 ± 0.1°).

Sample calculation

Maximum value

sin(("Deviation"+59.5)/2)/sin(29.45) = 1.368

Value without error

sin(("Deviation"+59)/2)/sin(29.5) = 1.361

Final value ..... n = 1.361 ± 0.007
