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 displacement law, the wavelength (in nanometers) at which the maximum energy is radiated is given by:
λmax = 2898/T
where T is the temperature in Kelvin. Substituting the temperature of the Sun, we get:
λmax = 2898/5800 = 0.5 μm = 500 nm.
Therefore, choice D is the correct answer.

The Sun Has a Surface Temperature of Approximately 5800 K
