Astar becomes a red giant and its surface temperature cools from 6000 k to 3000 k. its peak wavelength originally was 483 nm. what is its peak wavelength after it cools?

Peak wavelength

{lambda max}

= 9.7*EXP{-7}meter

Which is approximately,

1 micro-meter.

Explanation: lambda{max} which is peak wavelength is inversely proportional to temperature {T}.This is given by the wiens displacement law.

Lambda max

=max displacement{Xmax} / T

For the first case at T = 6000K

Lambda max = 483 nano-meter

=483*EXP{-9}meter.

So let's solve for max displacement {Xmax}.

Xmax = T*lambda max

= 6000*483*EXP{-9}

=2.898*EXP{-3}kelvin-meter

Xmax would be constant during Temperature change.

Therefore lambda max at 3000K would be,

Lambda max

= {2.898*EXP{-3} K-m} / 3000K

= 9.7*EXP{-7} meter

Which is approximately,

1*EXP{-6} meter= 1 micro-meter

NOTE: EXP used here means 10^.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
