Condition Of Grazing Emergence

Condition Of No Emergence

Given the limiting angle of a prism in which grazing incidence results in grazing emergence of a ray of light then how are 'A' and 'C' related?

A ray of light incident normally on one face of a prism ( mu =2) undergoes grazing emergence . The angle of the prism is

A ray of light is incident normally on the first refracting face of the prism of refracting angle A. The ray of light comes out at grazing emergences. If one half of the prism (shaded position) is knocked off, the same ray will:-

A ray of light is incident normally on the first refracting face of the prism of refracting angle A. The ray of light comes out at grazing emergences. If one half of the prism (shaded position) is knocked off, the same ray will:-

Find the refractive index of the liquid if a ray of light strikes on surface AB normally and then comes out from face AC at grazing emergence. (""_(a)mu_(g)H =3//2)
