Ram and his friends were trekking through a nearby forest. It started getting dark and they used a torch to light the path. Ram said the torch light can be related to geometry as a line because its shows a straight line path of light. But according to his friend Tom, the torch light can be related to a ray, not a line. Who's opinion do you think is correct and justify your answer.

A ray is a part of a line that has one end point and goes on infinitely in only one direction. It starts at a given point and extends in one direction infinitely. The same is happening when we switch on a torch light.
