Ray Optics and ...

For which of the two lenses $$L_1$$ and $$L_2$$ the chromatic aberration will be more if the radii of curvature of the surfaces of $$L_1$$ are less than those of $$L_2$$:

White light is incident normally on a glass slab. Inside the glass slab,

A luminous object is separated from a screen by distance $$d$$. A convex lens is placed between the object and the screen such that it forms a distinct image on the screen. The maximum possible focal length of this convex lens is

Find the refractive index of the glass which is a symmetrical convergent lens if its focal length is equal to the radius of curvature of its surface

The distance between principal focus and optical center of the lens is ________.

A vessel of depth t is half filled with a liquid having refractive index $$n_1$$ and the other half is filled with water of having refractive index $$n_2$$. The apparent depth of the vessel as viewed from top is:

According to the new cartesian sign convention, the ________ is taken as origin

Which coloured light scatters least by fog and smoke?

Which colour of light is scattered the most (maximum) in the atmosphere?

A quarter cylinder of radius $$R$$ and refractive index $$1.5$$ is placed on a table. A point object $$P$$ is kept at a distance of $$mR$$ from it as shown in figure. For what value of $$m$$ for which a ray from $$P$$ will emerge parallel to the table?
