Fill in the blanks to complete the following sentence
When light travels from a denser to a rarer medium, its speed ……………….
A ray of light strikes the surface at a rectangular glass slab such that the angle of incidence is 45o.
In each case, draw diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.
Using the curve, how do you infer that for given prism, the angle of minimum deviation δmin is unique for the given light?
