Where U _ { \ theta } and U _ { \ phi } represent the radiation intensity in a given direction contained in their respective E field component.
12.
Inverse square law would then suggest about 6.7 times the solar radiation intensity falling on a Mercury orbiter, than if it were in orbit around the Earth.
13.
The output power is obtained from the radiation intensity by integrating the latter over all solid angles d \ Omega = \ cos \ theta d \ theta d \ phi:
14.
Tyndall spectrally decomposed the radiation by use of a rock salt prism, which passed heat as well as visible rays, and measured the radiation intensity by means of a thermopile.
15.
It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data and was used to evaluate the Manned Space Flight Network tracking stations and Apollo Orbit Determination Program.
16.
The rate of absorption is proportional to the radiation intensity of the light, and also to the number of atoms currently in the ground state, " N " 1.
17.
The beam solid angle, represented as \ Omega _ A, is defined as the solid angle which all power would flow through if the antenna radiation intensity were constant at its maximal value.
18.
Sunburn effect ( as measured by the UV Index ) is the product of the sunlight spectrum ( radiation intensity ) and the erythemal action spectrum ( skin sensitivity ) across the range of UV wavelengths.
19.
Compared with arctic timberlines, alpine timberlines may receive fewer than half of the number of degree days ( > 10 �C ) based on air temperature because solar radiation intensities are greater at alpine than at arctic timberlines.
20.
From Eq . ( 10 ), we observe that the radiation intensity is negligible for \ xi \ gg 1 . " Critical frequency " is defined as the frequency when } } and 0 } }.
