b. Glass to air
Explanation:
Total internal reflection takes place when light passes from denser medium to rarer medium. Since glass is denser then air therefore total internal reflection takes place only in this pair .

In the figure, a light ray enters a glass slab at point
A at incident angle θ1 =
60.9o and then undergoes total internal reflection at
point B. What minimum value for the index of refraction of
the glass can be inferred from this information? Assume that the
index of refraction of air under standard temperature (0°C) and
pressure (1 atm) is 1.00029.

From within a diamond, a light ray is incident on the interface between diamond (nD = 2.4) and air. What is the critical angle for total internal reflection? FYI: the small value for tangentC implies that light is easily 'trapped' within a diamond, and eventually emerges after many internal reflections. A: 24.6 degrees

1. Why is it not possible for total internal reflection to occur when a light beam is passing from a medium of low optical density (air) into a medium of higher optical density ( glass or water). Explain fully. 2. When light is incident on an interface between two materials, the angle of the refracted ray depends on the wavelength, but the angle of the reflected ray does not. Why should this be true? Explain fully. 3. Sunlight and star...
