K.C.S.E Physics Q & A - MODEL 2002PP2QN01
Figure 1 shows the path of array of yellow light through a glass prism. The speed of yellow light in the prisms is 1.88 x 108m/s.
a) Determine the refractive index of the prism material for the light (speed of light in vacuum e = 3.0 x 108 ms-1)
b) Show on the figure the critical angle, c, and determine its value.
c) Given that r = 2 1 .2°, determine the angle O
d) On the same figure, sketch the path of the light after striking the prism if the prism was replaced by another of similar shape but lower refractive index. (Use dotted line for your answer)
