The peak wavelength of Betelgeuse is 828 nm
Explanation:
The relationship between surface temperature and peak wavelength of a star is given by Wien's displacement law:
where
is the peak wavelength
T is the surface temperature
is Wien's constant
For Betelgeuse, the surface temperature is approximately
T = 3500 K
Therefore, its peak wavelength is:

Lets make the original number of nuclides at the start is 100.
If 7/8 of 100 is decayed, that means 87.5 decayed.
And there is 1/8 left of the number of nuclide 100. Which is 12.5
How many Half lifes passed for 100 to become 12.5 is 3 Half-Lives.
Each Half-Life is 80 seconds so there is 240 seconds
The answer is that it takes 240 seconds.
If 7/8 of 100 is decayed, that means 87.5 decayed.
And there is 1/8 left of the number of nuclide 100. Which is 12.5
How many Half lifes passed for 100 to become 12.5 is 3 Half-Lives.
