• Define Mechanical Waves (CLO1)
• Distinguish between Transverse Waves and Compressional Waves (CLO1)
• Compare and Contrast Transverse and Compressional Waves (CLO3)
• Describe the Relationship between Frequency and Wavelength (CLO3)
• Explain How a Wave’s Amplitude is Related to the Wave’s Energy (CLO3)
• Calculate the Speed of a Wave (CLO5)
• Identify What Influences The Speed of Sound (CLO3)
• Discuss and Apply Various Properties of Sound (CLO3)
• Identify the Properties of Electromagnetic Radiation (CLO3)

                                     FIGURE 2

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

PART B – MEASURING WAVES

1. A tuning fork produces a wave at 280 Hz and with a wavelength of 1.5 m. Calculate its velocity.
2. A wave moves toward shore at 5.0 m/s. What is its wavelength if its frequency is 2.5 Hz?
3. The speed of light is 3 X 10⁸ 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?
4. 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.
5. What is the speed of sound in air at 45 degrees Celsius?
