4200 Joule/Kilogram K (J/kg∙K)

=

4.2 Kilojoule/Kilogram °C (kJ/kg∙°C)

Joule/Kilogram K : The joule per kilogram per kelvin is a SI derived unit of specific heat capacity. Its symbol is J/kg•K.

Kilojoule/Kilogram °C : The kilojoule per kilogram per degree Celsius is a unit of specific heat capacity, which is a decimal multiple of the metric unit of joule per kilogram per degree Celsius. Its symbol is kJ/kg•

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.
