उत्तर
Precautions to be observed to trace the path of a ray of light through a glass prism:
1. Make sure the prism taken is polished and not broken.
2. Make sure to look at the image through the proper eye level through the prism.
3. Sharp lines need to be drawn so that proper results can be observed.
4. The angle of incidence ideally should be 45o for a better outcome.
