1. Waves Practice
Tuesday, February 3rd, 2015

2. Do Now Study for the test on Wednesday
There will be a review session at 8
Do Now
You should have your sheet from yesterday
Complete Tuesday’s questions

3. Objectives SWBAT practice finding wavelength, frequency, and amplitude
SWBAT differentiate longitudinal and transverse waves by looking at examples
SWBAT explain wave interactions by looking at a picture

4. Vocabulary Amplitude Wavelength Frequency
measures the energy of a transverse wave. Measured from the equilibrium position to the top of a crest or the bottom of a trough (see vertical arrow)
Wavelength
length of a single wave cycle (horizontal arrow double sided arrow)
Frequency
# of waves that pass a point in a given amount of time measured in hertz (Hz)

5. Find the wavelength, amplitude, and frequency with units
The time of wave from start to finish is 2 seconds (frequency = # of waves/second)
The distance from the bottom of the wave to the top of the wave is 10 cm
The total length of the wave is 60 cm (wavelength = total distance/# of waves)

6. Find the wavelength, amplitude, and frequency with units
The time of wave from start to finish is 9 seconds
The distance from the bottom of the wave to the top of the wave is 30 cm
The total length of the wave is 54 cm

7. Classwork Practice worksheet
Identifying amplitude, frequency, wavelength
Longitudinal vs. Transverse waves
Refraction, reflection, diffraction, and interference
When you finish you can ask for the extension activity about seeing other wavelengths of the electromagnetic spectrum
