Answer 2

Answer:

The optical fiber has an acceptance angle of 15.07.

Explanation:

• A fiber that is flexible, transparent, and made up of silica or plastic having a diameter slightly thicker than the human hair is called optical fiber.
• Step index fibers are known to have a uniform core and cladding which is uniform with a smaller index of refraction and with only one index of refraction respectively.
• The ability to collect light from the source to save it inside the optical fiber by maintaining a total internal reflection is called the numerical aperture.

• The acceptance angle is referred to as ∝ (alpha).

                  Numerical aperture = sin∝ = √( n₁² - n₂²)

now,                            sin∝ = 0.26

                                    ∝ = sin⁻¹ (0.26) = 15.07

Therefore, the acceptance angle is 15.07.
