Transcript of Wave Properties

Wavelength Frequency Reflection Refraction Amplitude Crest Trough Tsunami bouncing back a wave off of a surface bending of a wave as it moves across the
boundary between one medium and another number of waves passing a point in one second,
measured in Hertz (Hz) lowest point of a wave distance a wave moves (oscillates) from
its resting position the distance between a point on one wave and the
same point on the next wave, such as crest to crest or
trough to trough. a giant ocean wave triggered by an earthquake,
landslide, volcanic eruption, or large falling
object, such as an iceberg or meteorite the highest part of a wave crest trough Wavelength Crest Trough http://www.tsunami.noaa.gov/ Click the link below to visit the NOAA
page on tsunamis: More information on frequency at:
http://www.qrg.northwestern.edu/projects/vss/docs/Communications/1-what-is-frequency.html As frequency increases,
energy increases, and wavelength
decreases resting position Click here to view a video about tsunami safety: http://www.tsunamiready.noaa.gov/media/Tsunami_know_what_to_do_Rev2.swf http://www.qrg.northwestern.edu/projects/vss/docs/Communications/2-how-does-reflection-affect-radio-waves.html The cornea and lens bend (refract) incoming light rays so they focus precisely on the retina at the back of the retina at the back of the eye. http://www.nei.nih.gov/healthyeyes/problems.asp Longitudinal Waves The type of wave made by sound energy. In longitudinal
waves, the particles of the medium vibrate ih the direction of
the moving energy. http://www.infoplease.com/dk/science/encyclopedia/energy-waves.html Transverse Waves Example of longitudinal waves:
sound waves The type of wave made by light energy,
moving up and down as it moves forward
through a medium of space Examples of transverse waves:
light
other types of electromagnetic energy
ocean (water) waves Medium A medium is the matter through which a
wave travels. Light waves do not need a medium,
but can travel through the vacuum of space Waves Wave Part
