If a source of power 4 kW produces 10^(20) photons // second, the radiation belongs to a part of the spectrum called:

If a source of power 4 kW produces 10^(20) photons per second,the radiatoin belongs to a part of the spectrum called

If a source of power 4 kW produces 10^20 photons per second, the radiation belongs to a part of spectrum called

If the source of power 4 kW produces 10^(20) photons/second , the radiation belongs to a part spectrum called

If the source of power 4 kW product 10^(20) photons //second , the radiation belongs to a part spectrum called

If the source of power 4 kW product 10^(20) photons //second , the radiation belongs to a part spectrum called

From source of power 4 kW,radiation emitted are such that photon are emitted at rate of 10^(20) photon/sec.This radiation will be in …..region of electromagnetic waves… []h=6.6xx10^(-34)Js

The average amount of energy received on a surface perpendicular to incoming radiation at the top of the atmosphere is called (1) Solar radiation (2) Electromagnetic spectrum (3) Solar constant (4) Electromagnetic constant
