Question

A formula from physics is λmax × T = 0.0029. This formula is called Wien's law, and it relates the wavelength of the peak of a blackbody spectrum (your answer to question 1), to the temperature of the object, in this case a pretend star, that is emitting the blackbody radiation. Use the formula to calculate the temperature of the star in degrees kelvin (K).

Hints

1. For the formula to give the correct answers, the wavelength must be in meters. To convert microns (μm) to meters, divide by 1000000 (one million).

2. The formula gives temperatures in degrees Kelvin.

Answer 1

Sanaa, you didn't give us "your answer to question 1" - the peak wavelength of the blackbody spectrum (λmax).  But, if you have it, you can solve for the temperature as follows:

 

(λmax)*T = 0.0029

 

T = 0.0029/λmax

 

Be sure to convert λmax to meters using hint 1.
