So we have several questions about wineslaw, which says like the peak wavelength for a given blackbody curve, occurs at this location where t is the temperature.
00:13
And so we're given two wavelengths, either 483 nanometers or 386 nanometers.
00:20
And we want to know which one of these corresponds to a hotter star.
00:23
Well, it would be the one with the smaller wavelength, because as you can see from wineslaw, the smaller the wavelength, the higher the temperature.
00:31
Our next question asks, what is the peak wavelength for the brightest main sequence star? and we're given two choices, either 64 nanometers or 386 nanometers, somewhere like that.
00:55
Now, this one we would need to know the size, because luminosity depends not only on the temperature, which we could find from wineslaw, but also the surface area of the star.
01:04
So you can't tell just from the wavelengths...
