Predict: How resonance can cause earthquakes to do greater damage to some buildings than others.

Question

Analyze: If two astronauts were able to go on a space walk without wearing suits. Explain why they would not be able to talk to one another.

Describe: How could you use interference to make a wave smaller in amplitude. Give a real world example.

Please help me!! I'm lost!

Answer 1

Are you listening in class? You seem to be having difficulty with the synthesis questions. Surely you discussed
a) resonance and positive interference.
b) sound waves require a physical media to transmit waves
c) negative interference.

Answer 2

Sorry, but we did not discuss in class, we only used a book and I've never learned about waves before.

Answer 3

If some of the vibrational waves of the earthquake have the same frequency or are a factor of the natural frequency of the buildings, then the buildings can start swaying in "tune" with the waves. It's like someone pushing a swing. The frequency of the push has to be the same as the natural frequency of the swing.

And sound waves need something to travel in. That's called a "medium". Vacuum exists in outer space, which means there is nothing there between the astronauts through which the waves can travel.
