Wilkingson Microwave Anisotrophy Probe
The
2.7 K Background Sky
The Wilkinson Microwave
Anisotropy Probe (WMAP) is a NASA satellite whose mission
was to survey the sky to measure the temperature of the radiant heat left
over from the Big Bang.
The goal of WMAP is to map out minute differences
in the Cosmic Microwave Background (CMB) radiation in
order to help test theories of the nature of the universe.
These
spectra are examples of what an astronomer would obtain when
aiming a spectrometer-equipped telescope to some galaxy far far away.
. .
The middle spectrum would be the spectrum
seen in the laboratory when the source and observer are not moving with
respect to each other.
The top spectrum suggests that the source
and the earth are moving toward each
other because the lines are shifted to the blue part of the spectrum.
The bottom spectrum
suggests that the source and the earth are moving
away from one another because the lines are shifted to
the red part of the spectrum.
The Doppler Redshift suggests
that
the universe is Expanding.
As the waves pass throught the slits they fan out and interfere with each other to produce the pattern on the screen.
This patterns reveals constructive and destructive intereference.
The Electric and Magnetic Fields move perpendicular to the propagation of the wave.
