The sun has a surface temperature of approximately 5800 K. At what wavelength does the maximum energy radiated by the sun occur?
A) 5800 nm
B) 300 nm
C) 174 nm
D) 500 nm
E) 3000 nm

Question

Quizplus · Accepted Answer

According to Wien's law, the wavelength of maximum energy radiation is inversely proportional to the temperature of the object. Using the formula λmax = b/T, where b is Wien's constant (2.898 x 10^-3 m·K), we can calculate the wavelength of maximum energy radiation for the sun:

λmax = 2.898 x 10^-3 m·K / 5800 K = 4.998 x 10^-7 m = 500 nm

Therefore, choice D is the correct answer.

The Sun Has a Surface Temperature of Approximately 5800 K
