What is a seismic wave?

Back

A seismic wave is an elastic wave generated by an earthquake or by a wave of other seismic sources, which travels through the Earth.

What are the two main types of seismic waves?

Back

The two main types of seismic waves are body waves (P-waves and S-waves) and surface waves.

What is the definition of amplitude in the context of seismic waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

What is a seismograph?

Back

A seismograph is an instrument that detects, records, and measures the vibrations produced by an earthquake.

What is the relationship between frequency and wavelength in seismic waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

What is the difference between P-waves and S-waves?

Back

P-waves (primary waves) are compressional waves that travel faster and can move through solids and liquids, while S-waves (secondary waves) are shear waves that only travel through solids.

What is the significance of the crest in a seismic wave?

Back

The crest is the highest point of a wave, representing the maximum displacement from the rest position.
