Question

Which of the following statements is true regarding how blackbody radiation changes as the temperature of the radiating object increases?
The maximum intensity increases, and the peak wavelength decreases.
The maximum intensity decreases, and the peak wavelength increases.
Both the maximum intensity and the peak wavelength decrease.
Both the maximum intensity and the peak wavelength increase.

Answer 1

The statement "The maximum intensity increases, and the peak wavelength decreases." is true regarding how black body radiation changes as the temperature of the radiating object increases. Temperature is directly proportional to intensity but inversely proportional to the wavelength.
