Graphing 1

1. Use a Taylor polynomial to show that, for large wavelengths, Planck's Law gives approximately the same values as the Rayleigh-Jeans Law. 2. Graph f as given by both laws in the same screen and comment on the similarities and differences. Use T= 5700K ( the temperature of the Sun). ( you may want to change from meters to t ...continues

Graph

Investigate how the graph of changes as T varies. (use Planck's Law.) In particular, graph for the stars Betelgeuse (T=3400 K), Procyon (T= 6400K), and Sirius( T= 9200K) as well as the Sun. How does the total radiation emitted (the area under the curve) vary with T? Use the graph to comment on why Sirius is known as a blue sta ...continues

Ichiro hits the ball and runs toward first base with a speed of 25 feet per second. The shortstop, who is exactly 40 feet in from third base on the baseline, gets the ball exactly 1.7 seconds after Ichiro started running (assume he runs at a constant rate.) At what rate is Ichiro's distance to the shortstop increasing at the m ...continues
