The blackbody graph indicates the peak wavelength and
Max spectral intensity of a star which can be used
to indicate temperature of star using wiens law:
2max= # so T - W . The wavelength peak can
2max
help us determine the colour of the star on the continuous
spectrum. If near 400mm = blue, 700hm = red. The area
under the graph tells us the power of star. Stephan S
law states P - AOTY which can be used to determine
area of a star by using the temperature + power found
from blackbody graph. The line absorption spectrum
can be used to identify elements absorbed from gases
at different wavelengths indicated by the black lines.
This helps us identify stars elements and it's generation.
The inverse square law can be used to determine
distance of star from earths surface.
