Calculate the time which light will take to travel normally through a glass plate of thickness `1 mm`. Refractive index of glass is `1.5`.

The time taken by a ray of light to travel through a glass slab of thickness 2 cm and refractive index 1.5 will be

The time taken by light to cross a glass slab of thickness 4 mm and refractive index 3 is

The optical path of monochromatic light is same if it travels 2 cm thickness of glass or 2.25 cm , thickness of water. If refractive index of glass is 1.5 , what is the refractive index of water ?

The optical path of a monochromatic light is the same if it travels through 4 cm of glass or 4.5 cm of water . If the refractive index of galss is 1.5, then the refractive index of water is

The wavelength of light in vacuum is lambda_(0) . When it travels normally through glass of thickness 't'. Then find the number of waves of light in ‘t’ thickness of glass (Refractive index of glass is mu )

Calculate time taken by light to travel 1 cm thickness of glass of mu = 1.5 .

A light ray from air is incident on a glass plate of thickness t and refractive index mu at an angle of incidence equal to the angle of total internal reflection of glass. Compute the displacement of the ray due to this plate in terms of thickness and refractive index of glass mu .
