The three statements that are true of a blackbody radiator are; A. It emits a range of wavelengths of EMR. C. It emits frequencies of EMR that depend on its temperature. D. It does not reflect much of the EMR it receives.
What is a blackbody radiator ?
A blackbody radiator is an object which absorbs all the electromagnetic radiation at varying frequencies and angles of incidence.
Blackbody radiators posses a cavity which does not allow heat to escape from the radiator.
The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, that are transverse waves formed by an electric field and a magnetic field perpendicular to it.
Therefore, we can conclude that the three statements that are true of a blackbody radiator are as listed.;
A. It emits a range of wavelengths of EMR.
C. It emits frequencies of EMR that depend on its temperature.
D. It does not reflect much of the EMR it receives.
Hence, the three statements that are true of a blackbody radiator are option A, C and D.
