Question

What is the value of "b" in Wien displacement law? Lambda max = b/T occurs when there is a bulk movement of thermal energy through the physical movement of atoms and molecules. Conduction Convection Radiation Study of the electromagnetic spectrum of a star indicates that the color star would be at a higher temperature than a color star. Blue, Red Red, Blue All stars are have same surface temperature regardless of color Cannot be determined Stephen Boltzmann Law is used in evaluation of Heat Transfer by Conduction Convection Radiation All of the above None of the above Blackbody absorbs all incident radiation, regardless of wavelength and direction. True False Cannot be determined Sun's Blackbody temperature is about 2500K 4000 K 5800 K 7000 K The equation: H= e sigma AT 4 represents heat transfer by - Conduction Convection Radiation Hot objects emit more radiation that colder objects True False Cannot be determined Units of micrometers are often used to characterize the wavelength of radiation. True False Cannot be determined The rate at which solar energy is received by a surface oriented perpendicular to the Sun's direction is called the solar constant. True False Cannot be determined

Explanation / Answer

1. B 2. A 3. A 4. C 5.A 6. C 7.C 8. C depends on this wavelength: Hot objects emit more of their light at short wavelengths, and cold objects emit more of their light at long wavelengths. 9. B 10. A
