- λ = _________ _________ What is the wavelength λ of ONE wave?
- a = _________ _________ What is the amplitude a?
- τ = _________ _________ What is the period τ of ONE wave?
- f = _________ _________ What is the frequency f?

- Explain the meaning and the significance of Sea Surface Temperatures with respect to El Niño.
- Explain the meaning and the significance of Southern Oscillation index with respect to El Niño.
- A student gathered the data seen in the table below.
- Plot the data on the graph.
- __________ __________ Calculate the experimental speed of sound based on the data. Include the units with your answer.
- __________The published value was 349 m/s. Calculate the percentage error for this data.
- __________ __________ Based on the experimental data, how long for a sound to travel 615.6 meters?
period τ = 1 ÷ (frequency f )
velocity ѵ = wavelength λ * frequency f
