Group 1: What is a Wave?

1 a) What is a (Water Surface) Wave? “One of a series of ridges that moves across the surface of a liquid (especially across a large body of water)” “One of a series of ridges that moves across the surface of a liquid (especially across a large body of water)” “A disturbance that propagates (moves) through space and time, usually with transference of energy” “A disturbance that propagates (moves) through space and time, usually with transference of energy”space timeenergyspace timeenergy A wave is a moving ripple of water across an ocean, lake, or other body of water, that is caused by the transfer of energy passed from one particle to another. A wave is a moving ripple of water across an ocean, lake, or other body of water, that is caused by the transfer of energy passed from one particle to another.

Group 2: Types of Waves

2a) Types of Waves 2a) Types of Waves *Ocean Surface Waves* *Ocean Surface Waves* Travel through water (i.e. waves for surfers) Travel through water (i.e. waves for surfers) Sound Waves Sound Waves A mechanical wave that travels through gases, liquids, solids and plasmas (i.e. sound waves of dolphins) A mechanical wave that travels through gases, liquids, solids and plasmas (i.e. sound waves of dolphins) Electromagnetic Waves Electromagnetic Waves Radio Waves (i.e. by lightning) Radio Waves (i.e. by lightning) Ultraviolet Light (i.e. by sunlight) Ultraviolet Light (i.e. by sunlight) Seismic Waves (Earthquakes) Seismic Waves (Earthquakes) Waves of force that travel through the Earth or other elastic bodies, for example as a result of an earthquake, explosion, or some other process that imparts forces Waves of force that travel through the Earth or other elastic bodies, for example as a result of an earthquake, explosion, or some other process that imparts forces

2b) Parts of a Wave

3) What are the Parts of a Wave? 3) What are the Parts of a Wave? Crest: The highest point (peak) of a wave Crest: The highest point (peak) of a wave Trough: Lowest point of a wave (where wave is smallest) Trough: Lowest point of a wave (where wave is smallest) Wavelength: The distance between two crests or two troughs Wavelength: The distance between two crests or two troughs Wave Height: The distance between a crest and a trough Wave Height: The distance between a crest and a trough

How Waves are Formed

Group 3: How are Waves Formed? Group 3: How are Waves Formed? Waves are formed by wind Waves are formed by wind We can also make waves with speed boats, etc. We can also make waves with speed boats, etc. 1. Winds blow across the surface of the sea 2. These winds pass their energy to water particles in the water 3. This energy transfer causes the water particles to move in a circular motion 4. As these moving water particles collide with others, they pass more energy to them, and create a wave. 5. The faster the wind blows, the faster these waves get
