Question

Which are uses of fiber optics? Check all that apply.

transmission of telephone signals
correction of vision problems
magnification of samples for viewing
examination of internal body parts
decoration purposes, such as lamps

Answer 1

Correct answers:
- Transmission of telephone signals
- Examination of internal body parts
- Decoration purposes, such as lamps

Why:
- Fiber-optic cables transmit large amounts of telephone/data signals as pulses of light.
- Fiber bundles are used in endoscopes to illuminate and image inside the body for medical examination.
- Decorative lamps and lighting (e.g., star‑ceiling lights) use fiber optics to carry light to remote points.

Not correct:
- Correction of vision problems — vision correction is done with lenses or laser surgery; fibers are not used to correct vision itself.
- Magnification of samples for viewing — magnification is provided by lenses (microscopes); fiber bundles can transmit images but do not themselves magnify.
