Solution 1. The deviation produced by the prism depends on the following four factors: The angle of incidence – As the angle of incidence increases, first the angle of deviation decreases and reaches to a minimum value for a certain angle of incidence. By further increasing the angle of incidence, the angle of deviation is found to increase. The material of prism (i.e., on refractive index) – For a given angle of incidence, the prism with a higher refractive index produces a greater deviation than the prism which has a lower refractive index. Angle of prism- Angle of deviation increases with the increase in the angle of prism. The colour or wavelength of light used- Angle of deviation increases wi...
