How does the deviation produced by a prism depend on the refraction index of its material.
Advertisements
उत्तर
Dependence of prism deviation on material refractive index: At a given incidence angle, a prism with a higher refractive index produces a larger deviation than one with a lower index.
Example: Compared to a crown glass prism with the same refractive angle, a flint glass prism exhibits greater variation.
Since µflint > µcrown
