The refractive index of red glass 1.644
The refractive index of blue glass is 1.664
therefore dispersive power of flint glass =1.664-1.644=0.02
I hope It will be helpful to you.
thank you.

option A that is 0.02 is the ans .
refractive indices of both the glasses are. ( 1.664 and 1.644)
therefore 1.644 will be subtracted from 1.664
1.664- 1.644= 0.02

No. Refractive index of red glass is 1.644 and blue glass is 1.664.
yep by mistake it was sended
It's ok medam. Thank you.
