The the maximum wavelength of the sun is 4.98275862 x 10^-7m or approximately 498.3nm (the peak on the graph is 499.6nm)
ReplyDeleteThe maximum wavelength when the temperature was doubled is 2.491 x 10^-7m or 249.1nm (the peak on the graph is 249.8nm)
when the temperature of the sun was doubled, the the maximum wavelength increased 17 times.
in the graphs, found that the higher the energy the shorter the wave length is.
ReplyDeleteweins law is not accurate. The curve in the graph because the graph showed it was 6.42x10^7
and the law said it was 4.987x10^-7
the doubled temp. the curve should be sixteen time as much power. the numbers are
1.0x10^12=3000
3.2x10^13=6000
3.125x10^24
In the graphs, I noticed that the higher the energy is, the higher the shorter the wave lengths.
ReplyDeleteWeins Law does not work. On the graph I got the number 6.42X10^7. When you plug it in the formula, I got the number 4.89X10^-7
When you have a curve that is 3000 and a curve that is 6000 then...
1.0X10^12 = 3000
3.2X10^13 = 6000
It would be 32 times as much power coming out of the star that is twice as hot.

ReplyDelete1. In Assignment 3 when you plug in the 5,800K into the temperature slot and then plug it into Wein's Law you get 499.6 nm, which is the peak of the graph as well.
2. When you double the temperature, the total energy increases by 17 times as much. The two temps I chose were 5,800K and 11,600K and their values were for 5,800K were about .5*10^14 and for 11,600 were about 8.5*10^14.
(2.89 x 10^-3)/5800 = 4.938 x 10^-7 m = 493.8 nm
ReplyDeletePower for temperature 5800 was 0.5 x 10^14
Power for temperature 11600 was 8.5 x 10^14
8.5 / 0.5 = 17 times as much power
