Question
When our star reaches the end of its main-sequence lifetime, it will become an M-class red giant (Unit 64) with a surface temperature of approximately 3300 K. How will its wavelength of peak radiation differ from the current value?
Step 1
First, we need to find the current wavelength of peak radiation for our star (the Sun). We can use Wien's Law for this, which states: λ_max = b / T where λ_max is the wavelength of peak radiation, b is Wien's constant (approximately 2.898 x 10^-3 m K), and T is Show more…

A star with a surface temperature of 20000 K, at what wavelength will it radiate its maximum energy?
The blackbody spectrum of a star with a surface temperature of $8,000 \mathrm{K}$ will peak at what wavelength? Give your answer in meters.
A star whose surface temperature is 4000 K has a peak wavelength of 725 nm, according to Wien's Law. If this star is in the Andromeda Galaxy, which is moving toward Earth at about 120 km/s, what would an observer on Earth see as the peak wavelength for this star?
