Answer:

• 1). Light goes in an orderly fashion. This can be demonstrated in the investigation when we can see a lit flame through a funnel just when it is kept straight. In any case in the event that we twist the channel, we can't see the light.

• 2). A shadow is thrown when light beams are halted by a misty item. The light which doesn't arrive at the article keep on passing while some of it is halted by the item. That is the reason a dull locale is shaped which is known as a shadow.

• 3). Light acts in a wave structure when it goes through an extremely little misty article. At that point light tends to twist around the article and not to pass straight. This is called diffraction of light.

• 4). So light carries on both as particles and as a wave. As a wave when diffraction happens and as particles regularly
