Thepicture above shows a source of light in the lower medium (thepurple dot), with the light shining on the origin, which is markedby the position of the green dot. The horizontal axis is theinterface separating one medium from another. In this case, all ofthe light reflects back into the lower medium.
Choose all the correct statements about this situation from thelist below.
A.The lower medium (where the source is) has a larger index ofrefraction than the upper medium.
B.The lower medium has the same index of refraction as the uppermedium.
C.The lower medium has a smaller index of refraction than the uppermedium.
D.The angle of incidence in this case is greater than the criticalangle for total internal reflection to occur.
E.The angle of incidence in this case is smaller than the criticalangle for total internal reflection to occur.
F.If the light source was moved to the position of the red dot inthe upper medium, and the light was incident on the origin again,the light would definitely experience total internalreflection.
G.If the light source was moved to the position of the red dot inthe upper medium, and the light was incident on the origin again,some light would refract into the lower medium, traveling towardthe position of the purple dot.
H.If the light source was moved to the position of the red dot inthe upper medium, and the light was incident on the origin again,some light would refract into the lower medium, but the light wouldnot travel toward the position of the purple dot.
