If a small angled prism, made of glass is immersed in a liquid of refractive index 1 and a ray of light is made incident on it, then

A glass prism of refractive index 1.5 and angle of prism 6^(@) is put in contact with another prism of refractive index 1.6 when a ray of light is made incident on this combination normally then it emerges out undeviated. The angle of second prism will be

A right angled isosceles glass prism is made from glass of refractive index 1.5.Show that a ray of light incident normally on the hypotneuse of this prism is deviated through 180^@ .

A right angled isosceles glass prism is made from glass of refractive index 1.5.Show that a ray of light incident normally on one of the equal sides of this prism is deviated through 90^@ .

An equilateral prism has its faces made of a transparent fiber sheet (having refractive index = 1.25) having thickness of 1 mm. The fibre prism is filled with a liquid of refractive index sqrt(2) . Find the deviation of a light ray incident on one face of such a prism at an angle of 45° .

A glass prism is immersed in a liquid of refractive index 1.4. If the refractive index of glass is 1.6 , find the limiting angle of the prism for emergence of ray through it.
