please help me out. thank you 2. A transparent silica block with refractive index of 1.457 was used in a study.(a). If a light source was incident normal to the silica block, determine itsreflectance.(b). Consider the case where the silica material was made into a long opticalfiber, about 300 km in length, with both ends polished flat. You are givena laser light source which power is sufficient to propagate across theentire length of the fiber with little attenuation and a dedicated sensorthat capable of measuring time intervals between light pulses,wavelength, and the intensity of light. Assuming there were no breaksin a fiber, produce a method to determine the length of the fiber usingonly one end of the fiber (nothing will be done for another end of thefiber). The methodology needs to be brief and concise, and includes thePhysics phenomenon that you would use.

please help me out. thank you

2. A transparent silica block with refractive index of 1.457 was used in a study.
(a). If a light source was incident normal to the silica block, determine its
reflectance.
(b). Consider the case where the silica material was made into a long optical
fiber, about 300 km in length, with both ends polished flat. You are given
a laser light source which power is sufficient to propagate across the
entire length of the fiber with little attenuation and a dedicated sensor
that capable of measuring time intervals between light pulses,
wavelength, and the intensity of light. Assuming there were no breaks
in a fiber, produce a method to determine the length of the fiber using
only one end of the fiber (nothing will be done for another end of the
fiber). The methodology needs to be brief and concise, and includes the
Physics phenomenon that you would use.
