**PART A - Waves**** FIGURE 1**

** FIGURE 2**

- Which figure represents a longitudinal wave?
- Which figure represents a transverse wave?
- Which part of a wave relates to its energy?
- As the wavelength of a wave in a uniform medium increases, its speed will _____.
- As these waves pass through their medium, is the medium carried along with them? Explain.
- What is the Universal Wave Equation? What does each variable in the formula represent? What units are used for each variable?
- Doubling the frequency of a wave source doubles the speed of the waves. (T or F)

**PART B – MEASURING WAVES**

- A tuning fork produces a wave at 280 Hz and with a wavelength of 1.5 m. Calculate its velocity.
- A wave moves toward shore at 5.0 m/s. What is its wavelength if its frequency is 2.5 Hz?
- The speed of light is 3 X 10
^{8}m/s (300,000,000 m/s). Red light has a wavelength of 7 X 10^{-7}m (0.0000007 m). What is its frequency? - Mac and Tosh are resting on top of the water near the end of the pool when Mac creates a surface wave. The wave travels the length of the pool and back in 25 seconds. The pool is 25 meters long. Determine the speed of the wave.
- What is the speed of sound in air at 45 degrees Celsius?
