Question

The dispersive power is maximum for the material

• A. Flint glass
• B. Crown glass
• C. Mixture of both
• D. None of the above

Answer 1

The correct option is A Flint glass

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.
