Quantum effects can be seen at the atomic and nano levels. why is nanotechnology more useful than atomic technology for creating new products? it is too small for dangerous quantum effects to apply. it is too large for most quantum effects to apply. it is smaller than the atomic level. it is large enough to build controllable devices.

nanotechnology is better than atomic technology because they are smaller than the atomic level

explanation: One nanometer (1 nm) is equal to 10-9 m or 0.000000001 m. A nanometer is 10 times smaller than the width of your DNA, and 10 times bigger than the size of an atom. Even though nanoscale is very small, it is at least 109 or 1,000,000,000 times bigger than a quark. Quarks are really, really, really small.

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.
