## frx 2 years ago i. Altair ii. Procyon iii. Epsilon Indi Which of the stars have longer wavelenght of maximum emission $\lambda _{\max}$ than the sun? How do I find this information? What does Wavelenght of maximum emission mean? The attached file showes the data from Starry Night which I should use

This is referring to the phenomenon of black body radiation. http://quantumfreak.com/introduction-to-blackbody-radiation/ The bottom graph shows that the hotter a star is (each hump is a different temperature) the brighter the light (the peak is higher) and the more the peak shifts toward high energy wavelengths (blue, UV). $\lambda _{\max}$ refers to the brightest wavelength being emitted. The equation that calculates $\lambda _{\max}$ based on temperature is b / T where b = 2.8977×10−3 and T is in Kelvin.
