Topics:Distinguish between waves that require a medium in which to propagate and those that do not. (LO2)Calculate the speed of waves through various media. (LO4)Calculate the speed of sound in air given the temperature. (LO4)Apply the equation relating velocity, frequency, and wavelength on a continuous wave. (LO4)Evaluate the Doppler effect and the mechanism for sonic booms. (LO3)Evaluate the concepts of constructive and destructive interference. (LO3)Distinguish between pure tones, complex tones, and noise. (LO3)Evaluate pitch, loudness, tone quality, and the physical quantities they depend upon. (LO2)Interpret results of experiments involving waves and sound. (LO5)Discuss everyday applications of waves and sound. (LO1)

1. Choose a discussion topic that uses physics topics covered in this module. Consider one of the following as good topic "starters" for discussion: (i) What were your "Aha!" moments as you worked through the material? (ii) How does this module's content relate to your professional career? Personal life? (iii) How does this module's content relate to current events? (iv) Did you more deeply explore a topic only covered lightly in the course materials? What did you discover? (v) What concepts (learning objectives) did you struggle with? What resources helped you overcome this hurdle? Do not post homework problems. 2. Create an engaging 3-paragraph initial post that ties one or more of the module's concepts to the real world. The paragraphs should address the following points: 0 Paragraph 1: Describe the physics concepts/topics you have chosen to discuss from this week's module, including, as appropriate, a reference to this week's readings on the topics, terminology with denitions, units, conventions, etc. 0 Paragraph 2: Summarize one or more impacts of the physics concepts to everyday life or aviation. 0 Paragraph 3: Either: (i) provide a real example, e.g., from an article or documented report of the aviation impact of this physics concept, or, (ii) give "your take" on the relevance and importance of this topic from your own perspective, by providing personal points of view or related experiences. 0 Length. Because your initial post will be scored on the degree to which you meet these standards, there is no set minimum word requirement. However, there is a set maximum word requirement conne your initial post to 500 words. Remember we are all reading each other's posts, and a succinctly written post is more likely to be read and responded to, thus furthering our discussion on that topic. 0 Graphics. Include a graphic, video, or image within your post (do not attach) that helps visualize some aspect of your initial post discussion. I To include a YouTube video, simply paste the video URL into your post, or embed the video using the Embed app on the toolbar. I To embed images from the web directly into the discussion post, review the Canvas I Ifyou have trouble embedding the image into your post, you can simply insert the image URL directly into your post
