Learning Goal: I can identify the different properties of waves. A wave is caused by a disturbance and transmits energy.   Waves are able to transmit energy, but not matter.

Label the parts of the wave. Crest Resting position Trough

Wavelength: Sdfdf It is measured crest to crest or trough to trough. ______________________ ____________________ h As _______________, ___________ decreases.

As energy increases, wavelength decreases. Learning Goal: I can measure the properties of waves Wavelength: how long a wave is Sdfdf It is measured crest to crest or trough to trough. Energy Wavelength As energy increases, wavelength decreases.

As _______________, ___________ increases. Amplitude: _______________ It is measure from crest to resting position or trough to resting position. ______________________ ____________________ h As _______________, ___________ increases.

As energy increases, amplitude increases. Learning Goal: I can measure the properties of waves Amplitude: How tall is a wave is It is measure from crest to resting position or trough to resting position. Energy Amplitude As energy increases, amplitude increases.

Frequency: __________________ _________________________ ____________________ h As _______________, ___________ increases.

As energy increases, frequency increases. Learning Goal: I can measure the properties of waves Frequency: how often a wave passes a certain point, usually measured in Hertz (Hz) Energy Frequency As energy increases, frequency increases.

Measure the wavelength and frequency Imaginary resting position 1.5 cm 7.5 cm 2 3 4 5 6 7 1 Wavelength 7.5 cm - 1.5 cm 6.0 cm Frequency – Count how many times the wave intersects with the resting position. Frequency – 7 Hz
