Exam-style question
Try this first
How does the diameter of an optical fibre affect the transmission of light?.
- A.Larger diameters improve transmission efficiency.
- B.Smaller diameters allow for more light to be transmitted.
- C.Diameter has no effect on light transmission.
- D.Larger diameters increase the risk of light loss.
Model answer
What a good answer should say
- Larger diameters improve transmission efficiency.
Explanation
Why this works
Larger diameters can reduce the effects of light loss due to scattering and allow for more light to be captured and transmitted, improving overall efficiency.
