Question

Figure shows the path of a Ray of light, through a rectangular glass block in a liquid of uniform density.
a) Does the light speed up or slow down in glass. Give reason for your answer.
b) What is the angular deviation of emergent Ray from the glass block with respect to the incident Ray?
c) Show with the help of ray diagram, the path of the ray when incident normally on the first surface of the glass block, through the block and the liquid.
d) What should the ratio of speed of light through the liquid to the speed through glass so that there is no reaction of light at the boundaries of the. ........... ( rest is given above)

​

Answer 1

Answer:

when light Ray's go rare medium to denser medium then speed of light get slow and light Ray's moves towards the normal is angle of deviatin
