Solution
6. As the refractive index contiuously changes the direction of the light ray also changes
contiuously, since when light ray enters into denser medium its direction will change.
7.Since air is optically rarer than water, the ray of light bends away from the normal at the point
of incidence when moving from water to air while it bends towards the normal while moving
from air to water. The normal at any point of a spherical bubble will pass through the center of
the bubble.
It is clearly visible that the air bag acts as a DIVERGING LENS (concave lens) in water.
