K.C.S.E Physics Q & A - MODEL 2014PP2QN12
Draw a ray diagram to show how a ray of light may be totally internally reflected two times in an isosceles right - angled glass prism. (Assume that the critical angle of glass is 42°)
K.C.S.E Physics Q & A - MODEL 2008PP2QN16
(a) State two conditions necessary for total internal reflection to occur
(b) Figure 9 shows a ray of light incident on the boundary between two media 1 and at an angle
Show that the refractive index for a ray of light traveling from medium 1 to medium 2 is given by:
M2 = 1/Sin θ
(c) Figure 10 shows a ray of light incident on one face of a block of ice of refractive index 1. 31 and totally reflected at the adjacent face
(i) Angle Φ
(ii) Angle x
(iii) Angle θ, the greatest angle for which the total internal reflection is possible
K.C.S.E Physics Q & A - MODEL 2003PP1QN15
One of the conditions for total internal reflection to occur is that angle of incidence must be greater than the critical angle of the medium. State the other condition
