Ever stopped to wonder at the most obviously overlooked thing?
What exactly is this thing called light?
Light travels only in a straight line. Is made up of 'packets'. Has a speed of almost 3,00,000 km/sec !!
Why is it that we can never see the speeding up or slowing down of a light ray? From the time it leaves it's source to the time it reaches us, there is no visible speeding up of a ray!!
Since it is made up of packets, if I were to hold my hand in the way of a beam, shouldn't the 'packets' drop down near my feet?
When light passes through a jar of water, shouldn't it slow down?
When I put my hand in the path of a beam, millions of 'packets' travelling at a terrifying pace of 3,00,000 km/sec should hurt me at least some. They don't. Why?? Because they don't have a 'body' that can stick?
Then how do clothes left in bright light fade eventually? Isn't the light that's falling on them taking away the colour bit by bit? (Of course it is)
If a beam of white light from a torch can light up an object on the table in a dark room, is it possible to 'vanish' an object on the table in a brightly lit room by using a torch that emits 'black light' so to say? (Here I am not referring to the 'black light' that is used commonly)
I have many more questions on light. Does anybody want to discuss?
