If you would like to replace the Unit 4 - Waves and Sound test grade, you may complete the remediation assignment below to be eligible for the test replacement. The answers must be HAND WRITTEN and turned in by Friday, 5/19. If you are unable to print this document, please include ALL the information below on a separate sheet of paper. , would like to replace the Unit 4 - Waves and Sound test, and have completed the below remediation assignment HAND WRITTEN for the unit. 1. Draw a transverse wave and label crest, wavelength, amplitude, trough, and rest line. 2. Draw a longitudinal wave and label compression, rarefaction, and wavelength. 3. Sound is a ( mechanical ; electromagnetic ), ( transverse ; longitudinal ) wave. Where is it the fastest? Slowest? Does not travel? Light is a ( mechanical ; electromagnetic ), ( transverse ; longitudinal ) wave. Where is it the fastest? Slowest? Does not travel? 4. What is the difference between a mechanical and electromagnetic wave? Give examples of each. 5. Define the following wave properties: a. Frequency: b. Period: c. Wavelength: d. Amplitude: 6. How do you change the speed of a wave? Give an example. 7. Write the formula that relates wavelength and frequency to wave speed, labeling each variable with name and unit. 8. Define each interference and draw a diagram to explain. a. Constructive interference: b. Destructive interference: 9. Draw a standing wave with 4 loops. Label a node, antinode, and wavelength. Nodes Antinodes waves If the string was 5m long, how long was the wavelength? 10. A bat is using echolocation in a cave that is 15.5 degrees Celsius. a. What is the speed of sound in the cave? b. If one of the cave walls was 25m away from the bat, how long would it take for the sound's echo to return to the bat? c. If the bat sends the sound at a frequency of 18,000Hz, what is the wavelength of the sound wave
