Advantage of optical fibre - Vidyadip

MCQ

Advantage of optical fibre

A
High bandwidth and $EM$ interference
B
Low bandwidth and $EM$ interference
C
High band width, low transmission capacity and no $EM$ interference
✓
High bandwidth, high data transmission capacity and no $EM$ interference

✓

Answer

Correct option: D.

High bandwidth, high data transmission capacity and no $EM$ interference

d
(d) Few advantages of optical fibres are that the number of signals carried by optical fibres is much more than that carried by the Cu wire or radio waves. Optical fibres are practically free from electromagnetic interference and problem of cross talks whereas ordinary cables and microwave links suffer a lot from it.

A convex lens (of focal length $20\, cm$) and a concave mirror, having their principal axes along the same lines, are kept $80\, cm$ apart from each other. The concave mirror is to the right of the convex lens. When an object is kept at a distance of $30\, cm$ to the left of the convex lens, its image remains at the same position even if the concave mirror is removed. The maximum distance of the object for which this concave mirror, by itself would produce a virtual image would be.....$cm$
