Exploring the Science of Waves in Surfing

What type of waves did Greg mention to Rochelle?

• Radio waves, gamma rays, microwaves

• Sound waves, light waves, radio waves

• Ocean waves, sound waves, gamma rays

• Water waves, sound waves, light waves

How do waves transfer energy?

• By displacing air only

• By creating vibrations in the medium only

• Through the movement of energy without moving matter

• By moving matter from one place to another

What is the amplitude of a wave?

• The length of one complete wave cycle

• The total height from crest to trough

• The distance between two crests

• The height from the center line to the crest

• Frequency

• Wavelength

• Amplitude

What does the frequency of a wave indicate?

• The distance between wave crests

• How often the wave occurs

• The height of the wave

• The speed of the wave

What is a standing wave?

• A wave that moves matter along its path

• A wave that transfers energy without moving matter

• A wave that only occurs in water

• A wave that results from two waves traveling in opposite directions

What happens to the water's movement as ocean waves pass?

• It moves towards the shore

• It moves away from the shore

• It moves up and down but not towards the shore

• It remains completely still

What medium do sound waves travel through?

• Only through water

• Only in a vacuum

• Through any form of matter

• Only through air

What is the difference between transverse and longitudinal waves?

• Transverse waves can only travel through solids

• Transverse waves travel in a right angle to the wave direction; longitudinal in the same direction

• Transverse waves move matter; longitudinal do not

• Longitudinal waves are faster than transverse waves

How is the speed of a wave calculated?

• Wavelength times frequency

• Frequency divided by wavelength

• Frequency plus wavelength

• Amplitude times wavelength
