A point source of light is kept at the centre of a solid transparent sphere. The sphere is surrounded by air . The refractive index of material of sphere for which the rays incident from point source on glass–air interface will suffer total internal reflection is: 
  • a)
    1.5
  • b)
    √2
  • c)
    2
  • d)
    Total internal reflection will not occur for any value of refractive index of the sphere
Correct answer is option 'D'. Can you explain this answer?
