D

All colours except green

Text Solution

Verified by Experts

The correct Answer is:
A
`sin theta _(c ) =(1)/( mu ) `
` ( theta _(c ))_(g ) lt ( theta _(c ))_(y ) lt (theta _(c ))_(0 )lt ( theta _(c ))_(R )`
`i= (theta_(c ))_(G )`
` I lt ( theta _(c ))_(Y ) lt ( theta _(C ))_(0 ) lt ( theta _(c ))_(R ) `
No TIR of Y ,O and R

In the diagram shown, a ray of light is incident on the interface between 1 and 2 at angle slightly greater than critical angle. The light surfers total internal reflection at this interface. After that the light ray falls at the interface of 1 and 3, and again it suffers total internal reflection. Which of the following relations should hold true?

Statement I: A ray is incident from outside on a glass sphere surrounded by air as shown in Figure. This ray may suffer total internal reflection at the second interface. Statement II: For a ray going from a denser to rarer medium, the ray may suffer total internal reflection.

A ray of light is incident on the surface of water. For what angle, the ray will undergo total internal reflection ?

Consider a light beam incident from air to a glass slab at Brewster's angle as shown in figure. A polaroid is placed in the path of the emergent ray at point P and rotated about an axis passing through the centre and pependicular to the plane of the plaroid.

A ray of light is incident on a glass prism of refractive index mu and refractive angle A. If it just suffers total internal reflection at the other face, obtain an expression relating the angle of incidence , angle of prism and critical angle.
