Calculate the dispersive power for crown glass from the given data $and μ_{V} = 1.523 μ_{R} = 1.5145$

Options:

Answer:

Solution:

Here, $μ_{V} = 1.523$ and $μ_{R} = 1.5145$ Mean refractive index, $μ = \frac{1.523 + 1.5145}{2} = 1.51875$ Dispersive power is given by, $ω = \frac{( μ _{V} - μ _{R} )}{( μ - 1 )} = \frac{1.523 - 1.5145}{( 1.51875 - 1 )} = 0.01639$
