Не совсем корректный вопрос. Что подразумеваемся под понятием протяженный?

Точечный источник света подразумевает одиночно установленный светильник с одной лампой, как правило их используют для создания атмосферы уюта, либо для подсветки чего-либо.

THE MAN WHO
RODE
A TORNADO
19-year-old high school student Matt Suter was visiting
his grandmother in her trailer in Missouri, USA. Earlier
in the day the weather was nice, but during the
afternoon dark clouds started gathering in the sky. By
night, it was raining heavily and strong winds were
blowing against the trailer.
It was then that Matt heard a strange loud noise. "It
was like ten aeroplanes around us," he said. Suddenly,
the walls, floor and ceiling started shaking. Furniture
was moving around in all directions. Terrified, Matt
tried to hold onto the sofa, but he couldn't. Something
lifted him off his feet and out as the walls of the trailer
were collapsing.

When Matt woke up, he was lying on the grass in the
middle of a field, 400 metres from the trailer! He had a
cut on his head and some small cuts and bruises on his
body. When he realised where he was, he went to a
neighbour for help. His neighbour wrapped him in a
blanket and drove him back to the trailer. His grandma
was OK, but the trailer was in pieces. Matt's grandma
was delighted to see him.
Matt was very lucky to escape disaster. No other person
on record has travelled that distance 'by tornado' and
lived to tell the story. For Matt it was a frightening
experience. "I always wanted to see a tornado," he
said. "But I definitely didn't want to be in one!"
