Presentation transcript:

Waves Waves are oscillations that carry energy and information from one place to another. Examples of waves: light, sound, electricity in a wire, cell phone transmissions, ripple in a pond Two types of waves: transverse and longitudinal

Transverse Waves Transverse wave: has its oscillations perpendicular to the direction of the wave. The wave moves left to right and the oscillation moves up and down Ocean waves are transverse waves transverse

Longitudinal Wave Longitudinal wave: has oscillations in the same direction the wave moves. Sound is a longitudinal wave longitudinal

Frequency, amplitude, and wavelength parts to a wave parts to a wave Frequency of a wave is a measure of how often it goes up and down and is measured in hertz (Hz) Amplitude of a wave is the height of the wave above the level surface Wavelength is the length of one complete cycle of a wave. Typically measured from crest to crest or trough to trough Pitch

Speed Speed describes how fast the wave moves Speed is frequency (f) times wavelength  Speed (m/sec) Frequency (hz) Wavelength (m)

What happens when a wave hits something? Reflection: bounce off and goes in a new direction. Refraction: bends as it crosses the edge Ripple Tank

Diffraction: bends as it goes around a corner or through an opening Absorption: amplitude gets smaller and smaller as it passes through the material
