Choose one of the options and show me that you have mastered the content. Your goal is to demonstrate that you fully comprehend the content and can apply and explain the science of the system you choose. (If you provide a response for more than one system, only the first system responses will be graded.)   Option 1: Electricity & Magnetism Calculate the cost of forgetting to turn off a bedroom light with three 40 Watt light bulbs and a 60 Watt desk lamp if they are left turned on for 6 hours. Assume the cost per kWh is 36 cents. (6 points) Describe what makes a permanent magnet magnetic. (6 points) Explain charging by induction in your own words and fully describe an example of an object being charged by induction. (8 points) Option 2: Waves, Light & Sound Describe a longitudinal wave in your own words and fully describe an example of a longitudinal wave. (6 points) Explain all processes involved with forming a rainbow. (6 points) Calculate the wavelength and frequency of a wave with 4 curves on a very long spring. The spring measures 4.5 meters when held horizontal. While the spring is in motion, students measure the time for 5 cycles of the standing wave to be 2.15 seconds. Calculate the wavelength and frequency of this wave.
