How can you determine the amplitude of a wave pattern?
Measure the length of each peak
Measure the length of the entire wave
Measure the height of each peak
Measure the width of each peak
If you use walking as a model for wavelength and amplitude, what would a short and high step represent?
The short wavelength, low amplitude
The short wavelength, high amplitude
The long wavelength, low amplitude
The long wavelength, high amplitude
What is the name of wave B, the wave that is felt first?
(a)
What do scientists watch at point 1 to warn people about coming earthquakes?
(a)
What detects the first waves and send messages to Earthquake centers at point 2?
(a)
What happens at point 3 in the diagram?
Longitudinal waves felt first from epicenter at the fault.
Sensors detect longitudinal waves and alert sent out to earthquake center.
Message sent to your device that calculates size and time of earthquake coming before transverse waves come.
Scientists watch for a bulge in Earth's surface
