How do i calculate temperature for a planet when given its spectrum graph and the values on the graph are in nm?
Have you looked in your textbook? What is the relationship between temperature and spectrum graph? If you have the formula, units don't matter, because you can easily convert from one to another.
It's with regards to a dwarf planet's temperature.
the graph shows the spectrum of the dwarf planet, with the peak intensity hitting in between 10^2 and 10^3.
I know that I have to use the Stefan-Boltzmann law: σ T^4, σ = 5.7 x 10^-8 watt/(m^2 x K^4), however T is in Kelvin and the values I'm given on the spectrum are in nm.
How would i figure out the temperature of this planet with the informatin I'm given? And how do i convert nm to K?
First of all, I think you mean "dwarf star"? 1m=10^9 nanometers. You may have to convert nanometers into meters by dividing by 10^9. Be sure NOT to confuse T in Kelvins by nanometers. The latter generally refers to wavelengths. Make all your units consistent.
no, I meant dwarf planet. That's exactly whats written on my assignment. to figure out the temperature, do i have to isolate t in the stefan law equation?
Why don't you state Stephan' Law and give us the variables that you are given. Will see what we can do. What does Stepahn's Law say as a formula?. Can you copy it from your book?
