Consider the following three cases. In all three cases, the
light is incident in medium 1, and all angles are measured from the
normal to the interface. Case A - the incident light is at 20
degrees to the normal in medium 1, and it refracts into medium 2 at
an angle of 10 degrees to the normal. Case B - the incident light
is at 40 degrees to the normal in medium 1, and it refracts into
medium 3 at an angle of 20 degrees to the normal. Case C - the
incident light is at 60 degrees to the normal in medium 1, and it
refracts into medium 4 at an angle of 30 degrees to the normal.
Select all the correct statements about this.
a The index of refraction of medium 1 is larger than that of all
three of the other media
b The index of refraction of medium 1 is smaller than that of
all three of the other media
c Medium 2 has the same index of refraction as medium 3 and as
medium 4
d The indices of refraction of the four media are all
different
e If you reversed the light in case A so it was incident at 10
degrees to the normal in medium 2 then the light would refract into
medium 1 at an angle of 20 degrees
