The angle of incidence from air to glass at point O on hemispherical glass slab is B. 0^{0}.

Explanation:

  • Angle of incidence is the angle made by incident ray with the normal on the interface of two mediums.
  • Normal is a line perpendicular to the surface interface.
  • The angle of incidence here is 0 degrees as the incident ray is along the normal of the hemispheric surface.
  • There is no refraction when the ray enters the glass slab, which shows that the incident ray is perpendicular to the surface interface.
