16
Q

What is a period of a wave?

A

The time taken for each wave to pass a point.

17
Q

Does a loud sound have a bigger amplitude?

A

YES!

18
Q

Does a low pitch sound have a shorter wavelength?

A

YES!

19
Q

What is a seismic wave?

A

It is a shock wave produced by an earthquake.

20
Q

What does “P” and “S” waves stand for?

A

P is primary waves which are longitudinal.

S is secondary waves which are transverse.

21
Q

What are the differences of the P and S wave travelling through earth?

A

P waves travel FASTER.

S waves CANNOT pass through the OUTER CORE, it is LIQUID.

22
Q

What effects do P and S waves have at the surface?

A

P waves cause a one off impact.

S wave causes shaking.

23
Q

Where is energy stored in a stationary wave?

A

In a stationary wave energy is stored rather than transferred to other locations.

24
Q

What is resonance?

A

The storing of energy in an oscillation or a stationary wave. The energy coming from an external source of appropriate frequency.
