Visible light waves are shorter than microwaves.
Gamma rays are higher frequency than Infared but are less dangerous.
Which of these is the order for the electromagnetic spectrum? *Abbreviation (Ex: R=Radio waves)*

How does the Doppler Effect help explain the Big Bang Theory?
Big Bang Theory says the universe is expanding. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is shrinking. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is shrinking. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is expanding. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
