MCQ
The dispersive power is maximum for the material
  • ✓
    Flint glass
  • B
    Crown glass
  • 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.
