Astronomy Review

The existence of the cosmic background radiation implies that

• the big bang model is wrong.
• the universe began in a hot, dense state.
• the universe did not have a moment of creation.
• the universe began in a cold, low-density state.

If an object is moving toward us, its spectrum will experience

• no shift
• red shift
• ROYGBIV shift
• blue shift

Why is the light from distant galaxies red-shifted?

• They produce more red light than nearby galaxies.
• They are moving away from us.
• The longer wavelengths are filtered out more by dust.
• They are moving toward us.

According to the doppler effect, objects in space that have high frequency light waves give off________ and those with low frequency light waves give off _____________.

• blue light; red light
• red light; blue light
• no light; some light
• some light; no light

What determines the path a star will follow?

• Gravity
• Lucky Charms
• Mass
• Bread Crumbs

According to the Doppler effect, what happens to the sound waves in a car moving away from you?

• They move more quickly, so their pitch increases
• Their frequency increases, so their pitch increases
• Their wavelength increases, so their pitch increases
