Albedo
Emissivity
experiences two properties
white
The ratio of power of radiation scattered from the body to the total power incident on the body
0 < a < 1
White surface= 1

An object absorbs energy from a source
occurs when
emits all wavelength of EM waves
and later
0 to 1
0 is a perfect reflector
1 is a perfect emitter
where
efficiency of bodies emitting energy
as a measure of
The ratio of heat radiated by an object and the energy radiated by a black body at the same temperature
P=eσAT^4
power emitted
depends on several factors
of a planet
latitude
terrain
season
which is
cloud formation
oceans (low) and snow (high)
Power emited by object/ Power emitted by a black body
