The angular dispersion of a prism depends on
A
the index of refraction only
B
the angle of incidence as well as the index of refraction
C
the angle of incidence only
D
the thickness of the prism
E
the prism angle
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Angle of Incidence: Changing the angle at which light strikes the prism affects the angle of refraction, subsequently influencing the dispersion of the light.
Index of Refraction: The prism's index of refraction determines the extent of light bending, which directly impacts the dispersion of different wavelengths.
