1. Explain the differences between a transverse and longitudinal wave. Include at least one example of each type of wave in your explanation. Your response should include at least 2 differences.
2. During a summer storm, a bolt of lightning is seen. A short time later, thunder is heard. If the lightning struck 4.50 km away, what was the time period between the lightning and thunder? The speed of sound in air is 331.0 m/s at 0.00 °C but the temperature is actually 28.0 °C. Show your work!
3. A sound wave with a wavelength of 1.25 meters travels through air at 340 m/s. What is the frequency of the wave? How would the frequency change if the same sound wave traveled through a copper pipe in which sound travels at a speed of 3560 m/s. Be sure to show your work and include the new frequency in your explanation.
