Understanding Surface Waves

The video tutorial explores surface waves, which are waves that travel along the surface of oceans. Unlike longitudinal or transverse waves, surface waves involve circular motion of particles at the surface. The video explains how this motion decreases with depth and discusses the occurrence of surface waves in oceans and during earthquakes, specifically Rayleigh waves. It also covers the anatomy of a surface wave, including terms like crest, trough, and wavelength, and explains wave properties such as amplitude and frequency.

What type of waves travel along the surface of the ocean?

• Longitudinal waves

• Transverse waves

• Surface waves

• Rayleigh waves

In surface waves, how do the particles of the medium move?

• Back and forth

• In a straight line

• In a circular motion

• Up and down

What happens to the circular motion of particles as you move deeper from the surface?

• It stops completely

• It increases

• It remains the same

• It decreases

Which type of surface waves are produced during an earthquake?

• Transverse waves

• Rayleigh waves

• Surface waves

• Longitudinal waves

What is the highest point of a surface wave called?

• Wavelength

• Amplitude

• Crest

• Trough

What is the term for the position a medium would take if there were no waves?

• Trough

• Undisturbed position

• Amplitude

• Crest

How is wavelength measured in a surface wave?

• From trough to crest

• From amplitude to amplitude

• From crest to crest

• From crest to trough

What does the amplitude of a wave measure?

• The frequency of the wave

• The wavelength of the wave

• The speed of the wave

• The energy of the wave

In what unit is the frequency of a wave measured?

• Meters

• Hertz

• Joules

• Seconds
