Because, there is destructive interference that occurs there.
Newton's rings are formed due to the interference of light waves reflected between a plano-convex lens and a flat glass surface in contact with each other. This interference creates alternating dark and bright rings, with the center being a dark spot. The varying thickness of the air gap between the lens and the glass surface causes the light waves to interfere constructively and destructively, resulting in the pattern of rings.
At the point of contact the lens and the glass plate, the thickness of the film is effectively zero but due to reflection at the lower surface of air film from denser medium, an additional path difference of Lemda/2 is introduced. consequently, the centre of newton ring is dark due to destructive interference.
Yes, Neptune does.There is another smaller dark spot called The Small Dark Spot, a southern cyclonic storm, which is also the second-most-intense storm. It is intially dark, but has a bright center core. Other dark spots are formed in Neptune's troposphere.
It's bright during most of the show ... although they do dim it somewhat during the trapeze lady ... and then it's dark after the audience is gone.
Yes it does. The spot is called 'The Great Dark Spot'
The white areas in an interference pattern represent constructive interference, where waves from two sources meet in phase to produce a brighter intensity. This occurs when the crests and troughs of waves align, reinforcing each other to create a brighter spot of light.
The names of Neptune's seas, or large dark spots, are: The Great Dark Spot The Dark Spot The Scooter The Small Dark Spot
The dark spot in the nucleus is called the nucleolus
The dark spot in the nucleus is called the nucleolus

Jupiter and Neptune have large dark spots caused by massive hurricanes. Jupiter's dark spot is known as the Great Red Spot, while Neptune's dark spot is called the Great Dark Spot.
In the NFL, pass interference is a penalty where a defensive player interferes with the ability of an eligible receiver to make a catch. The penalty for pass interference is typically a spot foul, meaning the offense is awarded the ball at the spot of the foul with an automatic first down.
