Answer 1

Refraction at both the surfaces appears as shown in the figure.
From geometry we see that both the angles from normal inside the sphere are equal(r). This results from being angles opposite to equal sides of a triangle.
Applying Snell's Law at both the surfaces gives,
$sin i = μ sin r$ (Surface 1)

$μ sin r = sin e$ (Surface 2)

Hence we see $i = e$ which means that total internal reflection does not take place.
However, Statement 2 is true. Total internal reflection takes place when a ray of light goes from denser to rarer medium, when incident with an angle greater than a critical angle. But this does not take place in the above case.

Answer 2

(Surface 1)

μ sin r = sin e

(Surface 2)

Hence we see

i = e

A ray is incident from outside on a glass sphere surrounded by air as shown in fig. This ray may suffer total internal reflection at the second interface.

For a ray going from a denser to rarer medium, the ray may suffer total internal reflection.

The light travelling from air to glass can suffer total internal reflection

Air is denser than glass.

A beam of white light is incident on glass air interface from glass to air such that green light just suffers total internet reflection. The colors of the light which will come out to air are

The light travelling from air to glass can suffer total internal reflection.

Air is rarer than glass.

White light is incident on the interface of glass and air as shown in the figure. If green light is just totally internally reflected then the emerging ray in air contains :

STATEMENT-1 : A ray is incident from outside on a glass sphere surrounded by air as shown. This ray may suffer total internal reflection at second interface.
STATEMENT 2 : For a ray going from denser to rarer medium, the ray may suffer total internal reflection.
