State Fermat’s principle. On the basis of thi
s principle, show that when light passes
from a medium of lower refractive index to a medium
of higher refractive index, it
bends towards the normal to the interface between t
he two media.

Please see the following question → link(http://freepdfhosting.com/0ed4fb0fe1.pdf) I have solved the first part, but instead of a positive sign, I get a negative one. This is due to a printing error in the question. Now in part b of the question, I get the answer by simply differentiating the optical path length with respect to 'closest distance' and I get the required answer, but I don't really understand why. Can you please tell why is the differential of optical path length equal to the angle turned by the light?
Note:- Make suitable approximations wherever necessary.

The velocity of light in the core of a step index fiber is 2.01x108 m/sec, and
the critical angle at the core-in cladding interfaces 80 degree .Determine the
numerical aperture and the acceptance angle at the fiber in air, assuming it
has a core diameter suitable for consideration by ray analysis .The velocity of
light in vacuum is 3x 108 m/sec
