Question

Sunspot Colors. If a sunspot has a temperature of 4200 K, what is the peak wavelength in units of nm using Wien's law(2.90x10⁶ /T)?

Answer 1

Answer #1

According to Wien's law. _max T = 2.989 x 10^-3 m K

therefore, _max = (2.989 x 10^-3 m K) / T

So, _max = (2.989 x 10^-3 m K) / 4200 K

_max = 690 x 10^-9 m or 690 nm
