Answer:
Everyday more than 99% of the light you see has been reflected towards you. There are very few examples of seeing unreflected light, like seeing the sun(which you shouldn’t) or seeing a bulb’s filament or a tubelight. Light direct from the source will be very bright. Also, lights illuminate a room only because rays are reflected from all corners of the room.
Thus, the statement that light travels in a straight line is never wrong. You only see the path of light on earth due to reflection by tiny atmospheric particles, this phenomenon is called the Tyndall effect.
even light emitted from torch light
