Electromagnetic Spectrum

If a star is being observed from Earth and it's light has shifted towards the blue side of the electromagnetic spectrum it would be...

• Moving towards the Earth

• Moving away from the Earth

• This is a trick question that cannot be answered

• It isn't a star, it is a very large blueberry.

Use the image to identify the motion of the object relative to Earth.  Compare the absorption spectra of the star to what the star would look like if it were not moving at all relative to Earth.

• It is not moving

• It is moving away from Earth (Redshift)

• It is moving towards Earth (Blueshift)

• It is moving towards Earth (Redshift)

Each element on the periodic table can be identified by its

• classification as a solid, liquid or gas.

• location on the table.

• ability to react to form compounds.

• unique spectral "fingerprint."

Spectral lines that are observed to be narrower & blue-shifted indicates that an object is

• moving away from Earth.

• showing transverse motion.

• moving towards Earth.

• showing radial motion.
