Which of the following figures shows the stages of development of the bean plant in correct order ?

If the figure below, PQRS denotes the path followed by a ray of light as it travels three media in succession. The absoulte refractive indices of the media are mu_(1),mu_(2) and mu_(3) respectively (The line segment RS' in the figure is parallel to PQ ) Then : .

A parallel beam of light is incident on a spherical drop of water (mu = 4//3) . Consider refraction of light at air-water interface, then reflection at water-air boundary (of course there will be refracted light energy in air as well), followed by refraction at water-air interface. Path of a typical ray refracted at A, then reflected at B and finally refracted at C has been shown in the Figure. Find the maximum value of angle delta . use sin^(-1) sqrt((20)/(27)) = 60^(@) and sin^(-1) sqrt((5)/(12)) = 40^(@) .

When a ray of monochromatic light is incident obliquely on the interface of two media,

A ray is incident on interface of two media at critical angle as shown in the figure.

In the diagram shown, light is incident on the interface between media 1 (refractive index n_(1) ) and 2 (refractive index n_(2) ) at angle slightly greater than the critical angle, and is totally reflected. The light is then also totally reflected at the interface between media 1 and 3 (refractive index n_(3) ), after which it travels in a direction opposite to its initial direction, The media must have a refractive indices such that. .

The following table given the values of refractive indices of a few media. Use this table to give an example of (i) a medium pair so that light speeds up when it goes from one of these media to another (ii) a medium pair so that light slows down when it goes from one of these media to another.
