The orbital radius of an electron in a hydrogen atom is 0.846 nm. What is its de Broglie wavelength?

The  value  is  

Explanation:

From the question we are told that

  The  orbital radius is  

Generally the de Broglie wavelength is mathematically represented as

substituting values

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.
