The refrating angle of a prism is `40^@` and the refractive index of its material is given by
`mu=1.25 + b/(delta^2)`
When a ray of light is incident normally on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.20.

If the wavelength of the incident light is 440 nm,find the value of b.
