JEE MAIN - Physics (2010 - No. 10)
As the beam enters the medium, it will
diverge
converge
diverge near the axis and converge near the periphery
travel as a cylindrical beam
Maelezo
In the medium, the refractive index will decreases from the axis forwards the periphery of the beam.
Therefore, the beam will move as one move from the axis to the periphery and hence the beam will converge.
Therefore, the beam will move as one move from the axis to the periphery and hence the beam will converge.
