Which form of energy travels faster than anything in the universe?
electrical energy
sound energy
heat energy
light energy
Is there sound in space?
No, because sound needs matter to travel through, and there is no matter in outer space.
Yes, because outer space has an atmosphere like Earth.
Is there light in outer space?
No, because light need matter to travel through.
Yes, because light doesn't need matter to travel through.
What is the Doppler Effect?
A change in frequency due to the relative motion of a wave source and an observer
When a wave overlaps with another wave
When a wave bounces off of another object
When a wave bends due to traveling through a different medium

What is the only thing that can change the speed of a wave?
change in frequency
change in wavelength
change in medium
the object traveling in the wave
A building on hard ground, made of concrete material, experiencing high frequency (.1sec period) waves during an earthquake are worst for:
tall buildings
medium buildings
small buildings
they'll all fall down....
A building on soft ground, made of concrete material, experiencing low frequency (4 sec period) waves during an earthquake are worst for:
tall buildings
medium buildings
small buildings
they'll all fall down....
