PARTS OF A WAVE USE THE WORDS TO LABEL THE PARTS OF THE WAVE: CREST, TROUGH, REST POSITION

PARTS OF A WAVE USE THE WORDS TO LABEL THE PARTS OF THE WAVE: CREST, TROUGH, REST POSITION crest trough rest position

THERE ARE 3 PROPERTIES OF WAVES: Amplitude, Wavelength, and Frequency

Amplitude Definition – the distance from rest position to the top of a crest or to the bottom of a trough (measures the energy) Examples: Light=Brightness, Sound=Loudness amplitude

Wavelength Definition – the distance between two crests or two troughs (measured in meters) wavelength

Frequency Definition – how many waves pass a set point in one second (measured in Hertz) Examples: 2 waves per second=2 Hz 1000 waves per second = 1000 Hz Light=Type of wave (electromagnetic) Sound=Pitch of the sound crests 3 crests and 3 troughs = 3 Hz troughs

FREQUENCY IS RELATED TO LIGHT: Lower Frequency Higher Frequency

FREQUENCY IS RELATED TO SOUND: Whales Songs – 25 Hz Click for whale song Human Speech – 200 Hz Cricket – 4, 500 Hz Click for crickets chirping Ultrasound – 1, 000 Hz
