C
Mixture of both
D
None of the above
✓
Answer
Correct option: A.
Flint glass
a Refractive Index of Flint Glass $(\mu=1.65)$ is relatively higher than Refractive Index of Crown Glass $(\mu=1.51)$. Since dispersive power is dependent on the Refractive Index so for Flint glass dispersive power is maximum.
