Question 2 • Physics

In which range is the peak wavelength of a star that is much hotter than the Sun most likely to be?

Answer
A
microwaves
B
ultraviolet light
C
infrared radiation
D
radio waves

Explanation

A star’s peak wavelength shifts to shorter wavelengths as its temperature increases (Wien’s law). Since the star is much hotter than the Sun, its peak is likely at a shorter wavelength, in the ultraviolet range, rather than in infrared, microwave, or radio wavelengths.
