Question

In multi mode graded index optical fiber,for light

There are many zigzag paths b)There is only one zigzag path
c)There are many curved paths
d)There is only one curved path​

Answer 1

Answer:

there is only one curved path

Answer 2

Multimode graded-index optical fibre, contain only one zigzag path, for light so option (B) is the correct answer.

• Graded index multimode fibre is a category of optical fibre where the refractive index is elevated at the axis of the core and then it reduces slowly towards the core-cladding interface.
• Light in step-index fibre fallows a zigzag way inside the fibre. The Refractive index of the core contains a constant value.
• Multi-mode optical fibre is a category of optical fibre primarily employed for communication within small lengths, like within a building or in an office.
