In everyday life and road safety reflectors on bikes, school bags, jackets and road signs make people visible to drivers at night when headlights shine on them. In science they show reflection of light: light bounces off shiny surfaces; telescopes and torches also use reflectors. Phrases: «bike reflector», «cat's eye reflectors», «reflector strips», «reflector vest».

note

Countable: «a reflector». From «reflect» plus «-or». Trap: a reflector does not glow by itself; it only shines when light hits it, so you still need lights on a bike at night.

In the corpora

• Telescopes gather light either with lenses (refractors) or with curved mirrors (reflectors).
• Cat's eyes, the little reflectors set into the middle of the road, were invented by Percy Shaw in England in 1934.
