CMB & Energy

What is CMB?

• visible to the human eye
• only located in certain places of the universe
• incredibly hot
• The remaining energy from the big bang

This is a picture of:

• The CMB
• The Milky Way
• The universe in the future
• A red shifted star

The cooking POT is being warmed up through this type of energy transfer

• Conduction

• Radiation
• Electrons

A wave with a large wavelength will have a ______ frequency and _____ energy

• low/low
• low/high
• high/high
• high/low

7. Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma rays
• Visible Light

• Infrared waves

What type of energy transfer makes noodles rise and fall in a pot on the stove?

• Conduction
• Radiation
• Convection
• Electrons

How does Cosmic Microwave Background (CMB) Radiation support the Big Bang Theory?

• CMB radiation is found everywhere in the universe.
• CMB radiation are useful in our everyday lives
• CMB radiation occurred at the time of the Big Bang and disappeared
• CMB radiation is found on only on the outer parts of the universe.

What type of heat transfer is responsible for the Earth being warmed by the Sun?

• Conduction
• Convection
• Radiation
• Electron

CMB radiation is radiation that was

• Originally Gamma rays, but red shifted to become x rays
• Originally low energy, but heated up when it hit the Earth
• Originally radiowaves, but shifted into microwaves
• Originally high energy, but cooled down as the universe grew

The early universe was extremely ______ and ______.

• hot/damp
• dense/hot
• dense/cold
• hot/bright
