Photoelectrons with a maximum speed of 7.00 × 10 6 m/s are ejected from a surface in the presence of light with a frequency of 8.00 × 10 14 Hz. If the mass of an electron is 9.10 × 10 -31 kg, calculate in joules the maximum kinetic energy of a single electron.

1 the 4 is sig

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.
