What is water glass

A glass is fully with water at 4^(@)C . Water overflows when the glass is

The optical paths traversed by a monochromatic of light are same while the ray either passes through a distance of 4 cm in glass or a distance of 4.5 cm in water .What is the refractive index of water if that of glass is 1.53?

The refractive index of water is 4/3 and that of glass is 3/2 with respect to vaccum. Calculate the refractive index of glass with respect to water.

A glass is filled with water up to 12.5 cm. The apparent depth of an object lying at the bottom of the glass is measured by a microscope to be 9.4 cm. Calculate the refractive index of water. If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope has to be moved to focus the object again?

If a glass prism is placed in side water then its dispersive power

Refractive index of glass is 1.5 and refractive index of water is 1.33. If the velocity in glass is 2 xx 10^(8) m * s^(-1) , is the velocity of light in water?
