Light from a helium-neon laser (633 nm) is used to illuminate two narrow slits. The interference pattern is observed on a screen 3 m behind the slits. Eleven bright fringes are seen on the screen, spanning a total separation of 52 mm from one end of the fringe pattern to the other. What is the spacing (in mm) between the slits

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
