The Doppler effect is Buy Fifa 14 Coins best described by the example of a passingsiren (or by Sheldon in this clipfrom The Big Bang Theory). When an object is movingand making sound, the waves ahead of it are bunched together whilebehind it they're spread out. This means that when it comes towardan observer, it seems high pitched, and when it passes there is anapparent drop in pitch where the waves being heard are more spreadout.

When it comes to light waves emitted by stars, the effect isessentially the same, but something called the Doppler blueshiftwill occur. The waves of electromagneitc radiation being given offby the stars will become shortened as they move at a relative speedtowards the observer. This means the frequency range will increase,causing radiation waves in space to move out of the visiblespectrum and into X-ray range, and radiation from the stars tobecome visible as cosmic microwave background radiation (CMBR).
